However, how these cortical flows interact with adjacent cytoplasmic components, changing their form and localization, and how this affects cytoplasmic organization and cell shape remains unclear. Here we show that in ascidian oocytes, the cooperative activities of cortical actomyosin flows and deformation of the adjacent mitochondria-rich myoplasm drive oocyte cytoplasmic reorganization and shape changes following fertilization. We show that vegetal-directed cortical actomyosin flows, established upon oocyte fertilization, lead to both the accumulation of cortical actin at the vegetal pole of the zygote and compression and local buckling of the adjacent elastic solid-like myoplasm layer due to friction forces generated at their interface. Once cortical flows have ceased, the multiple myoplasm buckles resolve into one larger buckle, which again drives the formation of the contraction pole—a protuberance of the zygote’s vegetal pole where maternal mRNAs accumulate. Thus, our findings reveal a mechanism where cortical actomyosin network flows determine cytoplasmic reorganization and cell shape by deforming adjacent cytoplasmic components through friction forces."}],"acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"Bio"},{"_id":"NanoFab"}],"related_material":{"link":[{"description":"News on ISTA Website","relation":"press_release","url":"https://ista.ac.at/en/news/stranger-than-friction-a-force-initiating-life/"}]},"language":[{"iso":"eng"}],"publication_status":"epub_ahead","publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","_id":"14846","department":[{"_id":"CaHe"},{"_id":"JoFi"},{"_id":"MiSi"},{"_id":"EM-Fac"},{"_id":"NanoFab"}],"date_updated":"2024-03-05T09:33:38Z"},{"abstract":[{"lang":"eng","text":"Reaching a high cavity population with a coherent pump in the strong-coupling regime of a single-atom laser is impossible due to the photon blockade effect.

The first high-quality resonator plays the role of a usual lasing cavity, and the second one presents a controlled dissipation channel, bolstering population inversion, and modifies the energy-level structure to lift the blockade. As confirmation of the lasing action, we observe conventional laser features such as a narrowing of the emission linewidth and external signal amplification.

Tunable directionality can be achieved by applying external magnetic fields that modify optical selection rules, by using nonlinear effects, or interactions with vibrations. However, these approaches are less suitable to control microwave photon propagation inside integrated superconducting quantum devices. Here, we demonstrate on-demand tunable directional scattering based on two periodically modulated transmon qubits coupled to a transmission line at a fixed distance. By changing the relative phase between the modulation tones, we realize unidirectional forward or backward photon scattering. Such an in-situ switchable mirror represents a versatile tool for intra- and inter-chip microwave photonic processors. In the future, a lattice of qubits can be used to realize topological circuits that exhibit strong nonreciprocity or chirality."}],"related_material":{"record":[{"relation":"research_data","id":"13124","status":"public"}]},"volume":14,"ec_funded":1,"file":[{"success":1,"file_id":"13123","checksum":"a857df40f0882859c48a1ff1e2001ec2","relation":"main_file","access_level":"open_access","content_type":"application/pdf","file_name":"2023_NaturePhysics_Redchenko.pdf","date_created":"2023-06-06T07:31:20Z","creator":"dernst","file_size":1654389,"date_updated":"2023-06-06T07:31:20Z"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["2041-1723"]},"publication_status":"published"},{"related_material":{"link":[{"description":"News on ISTA Website","url":"https://ista.ac.at/en/news/wiring-up-quantum-circuits-with-light/","relation":"press_release"}],"record":[{"id":"13122","status":"public","relation":"research_data"}]},"issue":"6646","volume":380,"ec_funded":1,"publication_identifier":{"eissn":["1095-9203"],"issn":["0036-8075"]},"publication_status":"published","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2301.03315","open_access":"1"}],"month":"05","intvolume":" 380","abstract":[{"text":"Quantum entanglement is a key resource in currently developed quantum technologies.

We call this - the quantum noise. Certain physical processes allow this quantum noise to get correlated in conjugate physical variables. These quantum correlations can be used to go beyond the potential of our inherently noisy universe and obtain a quantum advantage over the classical applications. \r\n\r\nQuantum noise being inherent also means that, at the fundamental level, the physical quantities are not well defined and therefore, objects can stay in multiple states at the same time. For example, the position of a particle not being well defined means that the particle is in multiple positions at the same time. About 4 decades ago, we started exploring the possibility of using objects which can be in multiple states at the same time to increase the dimensionality in computation. Thus, the field of quantum computing was born. We discovered that using quantum entanglement, a property closely related to quantum correlations, can be used to speed up computation of certain problems, such as factorisation of large numbers, faster than any known classical algorithm. Thus began the pursuit to make quantum computers a reality. \r\n\r\nTill date, we have explored quantum control over many physical systems including photons, spins, atoms, ions and even simple circuits made up of superconducting material. However, there persists one ubiquitous theme. The more readily a system interacts with an external field or matter, the more easily we can control it. But this also means that such a system can easily interact with a noisy environment and quickly lose its coherence. Consequently, such systems like electron spins need to be protected from the environment to ensure the longevity of their coherence. Other systems like nuclear spins are naturally protected as they do not interact easily with the environment. But, due to the same reason, it is harder to interact with such systems. \r\n\r\nAfter decades of experimentation with various systems, we are convinced that no one type of quantum system would be the best for all the quantum applications. We would need hybrid systems which are all interconnected - much like the current internet where all sorts of devices can all talk to each other - but now for quantum devices. A quantum internet. \r\n\r\nOptical photons are the best contenders to carry information for the quantum internet. They can carry quantum information cheaply and without much loss - the same reasons which has made them the backbone of our current internet. Following this direction, many systems, like trapped ions, have already demonstrated successful quantum links over a large distances using optical photons. However, some of the most promising contenders for quantum computing which are based on microwave frequencies have been left behind. This is because high energy optical photons can adversely affect fragile low-energy microwave systems. \r\n\r\nIn this thesis, we present substantial progress on this missing quantum link between microwave and optics using electrooptical nonlinearities in lithium niobate. The nonlinearities are enhanced by using resonant cavities for all the involved modes leading to observation of strong direct coupling between optical and microwave frequencies. With this strong coupling we are not only able to achieve almost 100\\% internal conversion efficiency with low added noise, thus presenting a quantum-enabled transducer, but also we are able to observe novel effects such as cooling of a microwave mode using optics. The strong coupling regime also leads to direct observation of dynamical backaction effect between microwave and optical frequencies which are studied in detail here. Finally, we also report first observation of microwave-optics entanglement in form of two-mode squeezed vacuum squeezed 0.7dB below vacuum level. \r\nWith this new bridge between microwave and optics, the microwave-based quantum technologies can finally be a part of a quantum network which is based on optical photons - putting us one step closer to a future with quantum internet.

However, this approach increases both the footprint and the parasitic cross-coupling and is ultimately limited by radiation losses—a potential roadblock for scaling up quantum processors to millions of qubits. In this work we present transmon qubits with sizes as low as 36 × 39 µm2 with 100-nm-wide vacuum-gap capacitors that are micromachined from commercial silicon-on-insulator wafers and shadow evaporated with aluminum. We achieve a vacuum participation ratio up to 99.6% in an in-plane design that is compatible with standard coplanar circuits. Qubit relaxationtime measurements for small gaps with high zero-point electric field variance of up to 22 V/m reveal a double exponential decay indicating comparably strong qubit interaction with long-lived two-level systems. The exceptionally high selectivity of up to 20 dB to the superconductor-vacuum interface allows us to precisely back out the sub-single-photon dielectric loss tangent of aluminum oxide previously exposed to ambient conditions. In terms of future scaling potential, we achieve a ratio of qubit quality factor to a footprint area equal to 20 µm−2, which is comparable with the highest T1 devices relying on larger geometries, a value that could improve substantially for lower surface-loss superconductors.

In application to continuous-variable harmonic-oscillator systems, such as the electromagnetic field, existing tomography methods typically reconstruct the state in discrete bases, and are hence limited to states with relatively low amplitudes and energies. Here, we overcome this limitation by utilizing a feed-forward neural network to obtain the density matrix directly in the continuous position basis. An important benefit of our approach is the ability to choose specific regions in the phase space for detailed reconstruction. This results in a relatively slow scaling of the amount of resources required for the reconstruction with the state amplitude, and hence allows us to dramatically increase the range of amplitudes accessible with our method."}],"oa_version":"Preprint","issue":"4","volume":108,"publication_status":"published","publication_identifier":{"issn":["2469-9926"],"eissn":["2469-9934"]},"language":[{"iso":"eng"}]},{"ddc":["530"],"date_updated":"2023-12-13T11:32:25Z","file_date_updated":"2023-07-18T08:43:07Z","department":[{"_id":"JoFi"}],"_id":"13227","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"journal_article","article_type":"original","language":[{"iso":"eng"}],"file":[{"date_created":"2023-07-18T08:43:07Z","file_name":"2023_NatureComm_Hassani.pdf","date_updated":"2023-07-18T08:43:07Z","file_size":2899592,"creator":"dernst","checksum":"a85773b5fe23516f60f7d5d31b55c200","file_id":"13248","success":1,"content_type":"application/pdf","access_level":"open_access","relation":"main_file"}],"publication_status":"published","publication_identifier":{"eissn":["2041-1723"]},"volume":14,"pmid":1,"oa_version":"Published Version","acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"abstract":[{"text":"Currently available quantum processors are dominated by noise, which severely limits their applicability and motivates the search for new physical qubit encodings. In this work, we introduce the inductively shunted transmon, a weakly flux-tunable superconducting qubit that offers charge offset protection for all levels and a 20-fold reduction in flux dispersion compared to the state-of-the-art resulting in a constant coherence over a full flux quantum. The parabolic confinement provided by the inductive shunt as well as the linearity of the geometric superinductor facilitates a high-power readout that resolves quantum jumps with a fidelity and QND-ness of >90% and without the need for a Josephson parametric amplifier. Moreover, the device reveals quantum tunneling physics between the two prepared fluxon ground states with a measured average decay time of up to 3.5 h. In the future, fast time-domain control of the transition matrix elements could offer a new path forward to also achieve full qubit control in the decay-protected fluxon basis.","lang":"eng"}],"intvolume":" 14","month":"07","scopus_import":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Hassani F, Peruzzo M, Kapoor L, Trioni A, Zemlicka M, Fink JM. 2023.

Here we report a study of the transport and microwave response of Josephson arrays with interactions exceeding this level. Contrary to expectations, we observe that the array resistance drops dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and then saturates at low temperature. Applying a magnetic field, we eventually observe a transition to a highly resistive regime. These observations can be understood within a theoretical picture that accounts for the effect of thermal fluctuations on the insulating phase. On the basis of the agreement between experiment and theory, we suggest that apparent superconductivity in our Josephson arrays arises from melting the zero-temperature insulator.","lang":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"},{"_id":"NanoFab"}],"month":"11","intvolume":" 19","scopus_import":"1","file":[{"date_updated":"2024-01-29T11:25:38Z","file_size":1977706,"creator":"dernst","date_created":"2024-01-29T11:25:38Z","file_name":"2023_NaturePhysics_Mukhopadhyay.pdf","content_type":"application/pdf","access_level":"open_access","relation":"main_file","file_id":"14899","checksum":"1fc86d71bfbf836e221c1e925343adc5","success":1}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1745-2481"],"issn":["1745-2473"]},"publication_status":"published","volume":19,"ec_funded":1},{"quality_controlled":"1","publisher":"Wiley","oa":1,"acknowledgement":"This work was supported by the National Key Research and Development Program of China (Grant no. 2022YFA1405200), the National Natural Science Foundation of China (Nos. 92265202), and the European Research Council (ERC CoG Q-ECHOS, 101001005).","date_published":"2023-12-01T00:00:00Z","doi":"10.1002/lpor.202200866","date_created":"2023-11-05T23:00:54Z","day":"01","publication":"Laser and Photonics Reviews","year":"2023","article_number":"2200866","title":"Microwave-optics entanglement via cavity optomagnomechanics","author":[{"last_name":"Fan","full_name":"Fan, Zhi Yuan","first_name":"Zhi Yuan"},{"first_name":"Liu","id":"45e99c0d-1eb1-11eb-9b96-ed8ab2983cac","orcid":"0000-0003-4345-4267","full_name":"Qiu, Liu","last_name":"Qiu"},{"last_name":"Gröblacher","full_name":"Gröblacher, Simon","first_name":"Simon"},{"first_name":"Jie","full_name":"Li, Jie","last_name":"Li"}],"article_processing_charge":"No","external_id":{"arxiv":["2208.10703"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"Z.Y.

Here, a new mechanism for preparing stationary entanglement between microwave and optical cavity fields in a cavity optomagnomechanical system is proposed. It consists of a magnon mode in a ferrimagnetic crystal that couples directly to a microwave cavity mode via the magnetic dipole interaction and indirectly to an optical cavity through the deformation displacement of the crystal. The mechanical displacement is induced by the magnetostrictive force and coupled to the optical cavity via radiation pressure. Both the opto- and magnomechanical couplings are dispersive. Magnon–phonon entanglement is created via magnomechanical parametric down-conversion, which is further distributed to optical and microwave photons via simultaneous optomechanical beamsplitter interaction and electromagnonic state-swap interaction, yielding stationary microwave-optics entanglement. The microwave-optics entanglement is robust against thermal noise, which will find broad potential applications in quantum networks and quantum information processing with hybrid quantum systems.","lang":"eng"}],"volume":17,"issue":"12","language":[{"iso":"eng"}],"publication_identifier":{"eissn":["1863-8899"],"issn":["1863-8880"]},"publication_status":"published","status":"public","article_type":"original","type":"journal_article","_id":"14489","department":[{"_id":"JoFi"}],"date_updated":"2024-01-30T14:36:42Z"},{"abstract":[{"lang":"eng","text":"We present a quantum-enabled microwave-telecom interface with bidirectional conversion efficiencies up to 15% and added input noise quanta as low as 0.16.

A general-purpose interface that can make use of single photon effects requires < 1 input noise quanta, which has remained elusive due to either low efficiency or pump induced heating. Here we demonstrate coherent electro-optic modulation on nanosecond-timescales with only 0.16+0.02−0.01 microwave input noise photons with a total bidirectional transduction efficiency of 8.7% (or up to 15% with 0.41+0.02−0.02), as required for near-term heralded quantum network protocols. The use of short and high-power optical pump pulses also enables near-unity cooperativity of the electro-optic interaction leading to an internal pure conversion efficiency of up to 99.5%. Together with the low mode occupancy this provides evidence for electro-optic laser cooling and vacuum amplification as predicted a decade ago.","lang":"eng"}],"acknowledged_ssus":[{"_id":"M-Shop"}],"oa_version":"Published Version","scopus_import":"1","month":"03","intvolume":" 13","publication_identifier":{"eissn":["20411723"]},"publication_status":"published","file":[{"checksum":"7c5176db7b8e2ed18a4e0c5aca70a72c","file_id":"10929","success":1,"access_level":"open_access","relation":"main_file","content_type":"application/pdf","date_created":"2022-03-28T08:02:12Z","file_name":"2022_NatureCommunications_Sahu.pdf","creator":"dernst","date_updated":"2022-03-28T08:02:12Z","file_size":1167492}],"language":[{"iso":"eng"}],"related_material":{"record":[{"status":"public","id":"12900","relation":"dissertation_contains"},{"status":"public","id":"13175","relation":"dissertation_contains"}]},"volume":13,"ec_funded":1},{"citation":{"ista":"Krause J, Dickel C, Vaal E, Vielmetter M, Feng J, Bounds R, Catelani G, Fink JM, Ando Y. 2022.

Using a copper cavity, unaffected by strong magnetic fields, we can probe solely the effect of magnetic fields on the transmons. We present data on a single-junction and a superconducting-quantum-interference-device (SQUID) transmon that are cooled down in the same cavity. As expected, the transmon frequencies decrease with increasing field, due to suppression of the superconducting gap and a geometric Fraunhofer-like contribution. Nevertheless, the thin-film transmons show strong magnetic field resilience: both transmons display microsecond coherence up to at least 0.65 T, and T1 remains above 1μs over the entire measurable range. SQUID spectroscopy is feasible up to 1 T, the limit of our magnet.

The dissipative photon loss via absorption, present to some extent in any optical cavity, is known to introduce thermo-optical effects and thereby impose fundamental limits on precision measurements. Here, we theoretically and experimentally reveal that such dissipative photon absorption can result in quantum feedback via in-loop field detection of the absorbed optical field, leading to the intracavity field fluctuations to be squashed or antisquashed. A closed-loop dissipative quantum feedback to the cavity field arises. Strikingly, this modifies the optical cavity susceptibility in coherent response measurements (capable of both increasing or decreasing the bare cavity linewidth) and causes excess noise and correlations in incoherent interferometric optomechanical measurements using a cavity, that is parametrically coupled to a mechanical oscillator. We experimentally observe such unanticipated dissipative dynamics in optomechanical spectroscopy of sideband-cooled optomechanical crystal cavitiess at both cryogenic temperature (approximately 8 K) and ambient conditions. The dissipative feedback introduces effective modifications to the optical cavity linewidth and the optomechanical scattering rate and gives rise to excess imprecision noise in the interferometric quantum measurement of mechanical motion. Such dissipative feedback differs fundamentally from a quantum nondemolition feedback, e.g., optical Kerr squeezing. The dissipative feedback itself always results in an antisqueezed out-of-loop optical field, while it can enhance the coexisting Kerr squeezing under certain conditions. Our result applies to cavity spectroscopy in both optical and superconducting microwave cavities, and equally applies to any dissipative feedback mechanism of different bandwidth inside the cavity. It has wide-ranging implications for future dissipation engineering, such as dissipation enhanced sideband cooling and Kerr squeezing, quantum frequency conversion, and nonreciprocity in photonic systems.","lang":"eng"}],"file_date_updated":"2022-05-09T07:10:51Z","department":[{"_id":"JoFi"}],"ddc":["530"],"date_updated":"2023-08-03T07:05:00Z","status":"public","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"11353"},{"quality_controlled":"1","publisher":"American Institute of Physics","oa":1,"acknowledgement":"We would like to thank all of the authors who contributed to\r\nthis Special Topic.

With demonstrations of quantum computers outperforming classical computers for a select range of problems,1–3 we have finally entered the noisy, intermediate-scale quantum (NISQ) computing era. While the quantum computers of today are technological marvels, they are not yet error corrected, and it is unclear whether any system will scale beyond a few hundred logical qubits without significant changes to architecture and control schemes. Today's quantum systems are analogous to the ENIAC (Electronic Numerical Integrator And Computer) and EDVAC (Electronic Discrete Variable Automatic Computer) systems of the 1940s, which ran on vacuum tubes. These machines were built on a solid, nominally scalable architecture and when they were developed, nobody could have predicted the development of the transistor and the impact of the resulting semiconductor industry. Simply put, the computers of today are nothing like the early computers of the 1940s. We believe that the qubits of future fault-tolerant quantum systems will look quite different from the qubits of the NISQ machines in operation today. This Special Topic issue is devoted to new and emerging quantum systems with a focus on enabling technologies that can eventually lead to the quantum analog to the transistor. We have solicited both research4–18 and perspective articles19–21 to discuss new and emerging qubit systems with a focus on novel materials, encodings, and architectures.

Here we are interested in the maximal amount of entanglement and the optimal entanglement generation rates that can be achieved with this scheme under realistic conditions taking, in particular, the finite amplifier bandwidth, waveguide losses, and propagation delays into account. By combining exact numerical simulations of the full network with approximate analytic results, we predict the optimal working point for the amplifier and the corresponding qubit-qubit entanglement under various conditions.

In contrast to classical\r\ncomputers based on bits that are represented by a single binary value, 0 or 1, quantum\r\nbits (or qubits) can be in a superposition of both. Thus, quantum computers can store\r\nand handle more information at the same time and a quantum advantage has already\r\nbeen demonstrated for two types of computational tasks. Rapid progress in academic\r\nand industry labs accelerates the development of superconducting processors which may\r\nsoon fnd applications in complex computations, chemical simulations, cryptography, and\r\noptimization. Now that these machines are scaled up to tackle such problems the questions\r\nof qubit interconnects and networks becomes very relevant. How to route signals on-chip\r\nbetween diferent processor components? What is the most efcient way to entangle\r\nqubits? And how to then send and process entangled signals between distant cryostats\r\nhosting superconducting processors?\r\nIn this thesis, we are looking for solutions to these problems by studying the collective\r\nbehavior of superconducting qubit ensembles. We frst demonstrate on-demand tunable\r\ndirectional scattering of microwave photons from a pair of qubits in a waveguide. Such a\r\ndevice can route microwave photons on-chip with a high diode efciency. Then we focus\r\non studying ultra-strong coupling regimes between light (microwave photons) and matter\r\n(superconducting qubits), a regime that could be promising for extremely fast multi-qubit\r\nentanglement generation. Finally, we show coherent pulse storage and periodic revivals\r\nin a fve qubit ensemble strongly coupled to a resonator. Such a reconfgurable storage\r\ndevice could be used as part of a quantum repeater that is needed for longer-distance\r\nquantum communication.\r\nThe achieved high degree of control over multi-qubit ensembles highlights not only the\r\nbeautiful physics of circuit quantum electrodynamics, it also represents the frst step\r\ntoward new quantum simulation and communication methods, and certain techniques\r\nmay also fnd applications in future superconducting quantum computing hardware.\r\n","lang":"eng"}],"acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"},{"_id":"EM-Fac"}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"month":"09","citation":{"chicago":"Redchenko, Elena. “Controllable States of Superconducting Qubit Ensembles.” Institute of Science and Technology Austria, 2022. https://doi.org/10.15479/at:ista:12132.","ista":"Redchenko E. 2022.

Bluefors and Zurich Instruments have supported the growth of this field from the 2010s onwards by providing well-engineered and reliable measurement infrastructure [2]– [6]. Having a long and stable qubit lifetime is a critical system property. Therefore, considerable effort has already gone into measuring qubit energy-relaxation timescales and their fluctuations, see Refs. [7]–[10] among others. Accurately extracting the statistics of a quantum device requires users to perform time consuming measurements. One measurement challenge is that the detection of the state-dependent\r\nresponse of a superconducting resonator due to a dispersively-coupled qubit requires an inherently low signal level. Consequently, measurements must be performed using a microwave probe that contains only a few microwave photons. Improving the signal-to-noise ratio (SNR) by using near-quantum limited parametric amplifiers as well as the use of optimized signal processing enabled by efficient room temperature instrumentation help to reduce measurement time. An empirical observation for fixed frequency transmons from recent literature is that as the energy-relaxation time 𝑇𝑇1 increases, so do its natural temporal fluctuations [7], [10]. This necessitates many repeated measurements to understand the statistics (see for example, Ref. [10]). In addition, as state-of-the-art qubits increase in lifetime, longer\r\nmeasurement times are expected to obtain accurate statistics. As described below, the scaling of the widths of the qubit energy-relaxation distributions also reveal clues about the origin of the energy-relaxation.","lang":"eng"}],"place":"Helsinki, Finland","month":"06","alternative_title":["Bluefors Blog"],"quality_controlled":"1","publisher":"Bluefors Oy","main_file_link":[{"url":"https://bluefors.com/blog/application-note-qubit-energy-relaxation-statistics-bluefors-quantum-measurement-system/","open_access":"1"}],"oa":1,"user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2022-01-19T09:11:39Z","citation":{"ista":"Simbierowicz S, Shi C, Collodo M, Kirste M, Hassani F, Fink JM, Bylander J, Perez Lozano D, Lake R. 2021.

Second, we demonstrate that the Keysight system (controlled using Labber) provides a straightforward solution to perform these characterization measurements.

While the corresponding rf superconducting quantum interference device Hamiltonian was introduced as a quadratic quasi-one-dimensional potential approximation to describe the fluxonium qubit implemented with long Josephson-junction arrays, in this work we implement it directly using a linear superinductor formed by a single uninterrupted aluminum wire. We present a large variety of qubits, all stemming from the same circuit but with drastically different characteristic energy scales. This includes flux and fluxonium qubits but also the recently introduced quasicharge qubit with strongly enhanced zero-point phase fluctuations and a heavily suppressed flux dispersion.

The Josephson junction has revolutionized the field of superconducting circuits as a non-linear dissipation-less circuit element and is used in almost all superconducting qubit implementations since the 90s. On the other hand, the superinductor is a relatively new circuit element introduced as a key component of the fluxonium qubit in 2009. This is an inductor with characteristic impedance larger than the resistance quantum and self-resonance frequency in the GHz regime. The combination of these two elements can occur in two fundamental ways: in parallel and in series. When connected in parallel the two create the fluxonium qubit, a loop with large inductance and a rich energy spectrum reliant on quantum tunneling. On the other hand placing the two elements in series aids with the measurement of the IV curve of a single Josephson junction in a high impedance environment. In this limit theory predicts that the junction will behave as its dual element: the phase-slip junction. While the Josephson junction acts as a non-linear inductor the phase-slip junction has the behavior of a non-linear capacitance and can be used to measure new Josephson junction phenomena, namely Coulomb blockade of Cooper pairs and phase-locked Bloch oscillations. The latter experiment allows for a direct link between frequency and current which is an elusive connection in quantum metrology. This work introduces the geometric superinductor, a superconducting circuit element where the high inductance is due to the geometry rather than the material properties of the superconductor, realized from a highly miniaturized superconducting planar coil. These structures will be described and characterized as resonators and qubit inductors and progress towards the measurement of phase-locked Bloch oscillations will be presented.","lang":"eng"}],"oa_version":"Published Version","alternative_title":["ISTA Thesis"],"month":"08"},{"department":[{"_id":"JoFi"}],"file_date_updated":"2021-08-09T12:23:13Z","ddc":["530"],"date_updated":"2023-10-17T12:54:54Z","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","_id":"9815","issue":"4","volume":6,"language":[{"iso":"eng"}],"file":[{"file_name":"2021_QuantumScienceTechnology_Mobassem.pdf","date_created":"2021-08-09T12:23:13Z","file_size":2366118,"date_updated":"2021-08-09T12:23:13Z","creator":"cchlebak","file_id":"9836","checksum":"b15c2c228487a75002c3b52d56f23d5c","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"publication_status":"published","publication_identifier":{"eissn":["2058-9565"]},"intvolume":" 6","month":"07","scopus_import":"1","oa_version":"Published Version","abstract":[{"text":"The quantum bits (qubits) on which superconducting quantum computers are based have energy scales corresponding to photons with GHz frequencies. The energy of photons in the gigahertz domain is too low to allow transmission through the noisy room-temperature environment, where the signal would be lost in thermal noise. Optical photons, on the other hand, have much higher energies, and signals can be detected using highly efficient single-photon detectors. Transduction from microwave to optical frequencies is therefore a potential enabling technology for quantum devices. However, in such a device the optical pump can be a source of thermal noise and thus degrade the fidelity; the similarity of input microwave state to the output optical state. In order to investigate the magnitude of this effect we model the sub-Kelvin thermal behavior of an electro-optic transducer based on a lithium niobate whispering gallery mode resonator. We find that there is an optimum power level for a continuous pump, whilst pulsed operation of the pump increases the fidelity of the conversion.","lang":"eng"}],"title":"Thermal noise in electro-optic devices at cryogenic temperatures","article_processing_charge":"Yes","external_id":{"arxiv":["2008.08764"],"isi":["000673081500001"]},"author":[{"first_name":"Sonia","last_name":"Mobassem","full_name":"Mobassem, Sonia"},{"first_name":"Nicholas J.","full_name":"Lambert, Nicholas J.","last_name":"Lambert"},{"id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87","first_name":"Alfredo R","last_name":"Rueda Sanchez","full_name":"Rueda Sanchez, Alfredo R","orcid":"0000-0001-6249-5860"},{"id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","first_name":"Johannes M","last_name":"Fink","orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M"},{"last_name":"Leuchs","full_name":"Leuchs, Gerd","first_name":"Gerd"},{"first_name":"Harald G.L.","last_name":"Schwefel","full_name":"Schwefel, Harald G.L."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Mobassem S, Lambert NJ, Rueda Sanchez AR, Fink JM, Leuchs G, Schwefel HGL. 2021.

Electro-opto-mechanical devices are currently one of the leading approaches to realize ultra-sensitive, low-loss transducers for an emerging quantum information technology. Here we present an on-chip microwave frequency converter based on a planar aluminum on silicon nitride platform that is compatible with slot-mode coupled photonic crystal cavities. We show efficient frequency conversion between two propagating microwave modes mediated by the radiation pressure interaction with a metalized dielectric nanobeam oscillator. We achieve bidirectional coherent conversion with a total device efficiency of up to ~60%, a dynamic range of 2 × 10^9 photons/s and an instantaneous bandwidth of up to 1.7 kHz. A high fidelity quantum state transfer would be possible if the drive dependent output noise of currently ~14 photons s^−1 Hz^−1 is further reduced. Such a silicon nitride based transducer is in situ reconfigurable and could be used for on-chip classical and quantum signal routing and filtering, both for microwave and hybrid microwave-optical applications.","lang":"eng"}],"volume":5,"issue":"3","ec_funded":1,"file":[{"content_type":"application/pdf","access_level":"open_access","relation":"main_file","checksum":"8f25f05053f511f892ae8fa93f341e61","file_id":"8072","date_updated":"2020-07-14T12:48:08Z","file_size":2600967,"creator":"cziletti","date_created":"2020-06-30T10:29:10Z","file_name":"2020_QuantumSciTechnol_Fink.pdf"}],"language":[{"iso":"eng"}],"publication_identifier":{"eissn":["20589565"]},"publication_status":"published","status":"public","article_type":"original","type":"journal_article","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"8038","department":[{"_id":"JoFi"}],"file_date_updated":"2020-07-14T12:48:08Z","ddc":["530"],"date_updated":"2023-08-22T07:49:01Z"},{"year":"2020","isi":1,"has_accepted_license":"1","publication":"Nature Communications","day":"08","date_created":"2020-09-18T10:56:20Z","date_published":"2020-09-08T00:00:00Z","doi":"10.1038/s41467-020-18269-z","acknowledgement":"We thank Yuan Chen for performing supplementary FEM simulations and Andrew Higginbotham, Ralf Riedinger, Sungkun Hong, and Lorenzo Magrini for valuable discussions.

In this work we utilize the unique opportunities of silicon photonics, cavity optomechanics and superconducting circuits to demonstrate a fully integrated, coherent transducer interfacing the microwave X and the telecom S bands with a total (internal) bidirectional transduction efficiency of 1.2% (135%) at millikelvin temperatures. The coupling relies solely on the radiation pressure interaction mediated by the femtometer-scale motion of two silicon nanobeams reaching a Vπ as low as 16 μV for sub-nanowatt pump powers. Without the associated optomechanical gain, we achieve a total (internal) pure conversion efficiency of up to 0.019% (1.6%), relevant for future noise-free operation on this qubit-compatible platform.","lang":"eng"}],"oa_version":"Published Version","intvolume":" 11","month":"09","date_updated":"2023-08-22T09:27:12Z","ddc":["530"],"file_date_updated":"2020-09-18T13:02:37Z","department":[{"_id":"JoFi"}],"_id":"8529","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","keyword":["General Biochemistry","Genetics and Molecular Biology","General Physics and Astronomy","General Chemistry"],"status":"public"},{"_id":"13056","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"type":"research_data_reference","ddc":["530"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-08-22T09:27:11Z","citation":{"mla":"Arnold, Georg M., et al.

Its advantage is particularly evident at low signal powers, a promising feature for applications such as noninvasive biomedical scanning or low-power short-range radar. Here, we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path. Starting from experimental data, we also simulate the case of perfect idler photon number detection, which results in a quantum advantage compared with the relative classical benchmark. Our results highlight the opportunities and challenges in the way toward a first room-temperature application of microwave quantum circuits."}],"month":"05","intvolume":" 6","scopus_import":"1","ddc":["530"],"date_updated":"2023-08-24T11:10:49Z","department":[{"_id":"JoFi"}],"file_date_updated":"2020-07-14T12:48:05Z","_id":"7910","status":"public","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"day":"06","publication":"Science Advances","isi":1,"has_accepted_license":"1","year":"2020","date_published":"2020-05-06T00:00:00Z","doi":"10.1126/sciadv.abb0451","date_created":"2020-05-31T22:00:49Z","publisher":"AAAS","quality_controlled":"1","oa":1,"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"mla":"Barzanjeh, Shabir, et al. “Microwave Quantum Illumination Using a Digital Receiver.” Science Advances, vol. 6, no. 19, eabb0451, AAAS, 2020, doi:10.1126/sciadv.abb0451.","short":"S.

In contrast to nonlinear optics, electro-optic devices so far require classical modulation fields whose variance is dominated by electronic or thermal noise rather than quantum fluctuations. Here we demonstrate bidirectional single-sideband conversion of X band microwave to C band telecom light with a microwave mode occupancy as low as 0.025 ± 0.005 and an added output noise of less than or equal to 0.074 photons. This is facilitated by radiative cooling and a triply resonant ultra-low-loss transducer operating at millikelvin temperatures. The high bandwidth of 10.7 MHz and total (internal) photon conversion\r\nefficiency of 0.03% (0.67%) combined with the extremely slow heating rate of 1.1 added output noise photons per second for the highest available pump power of 1.48 mW puts near-unity efficiency pulsed quantum transduction within reach. Together with the non-Gaussian resources of superconducting qubits this might provide the practical foundation to extend the range and scope of current quantum networks in analogy to electrical repeaters in classical fiber optic communication."}],"acknowledged_ssus":[{"_id":"M-Shop"}],"title":"Bidirectional electro-optic wavelength conversion in the quantum ground state","author":[{"first_name":"William J","id":"29705398-F248-11E8-B48F-1D18A9856A87","last_name":"Hease","full_name":"Hease, William J","orcid":"0000-0001-9868-2166"},{"last_name":"Rueda Sanchez","orcid":"0000-0001-6249-5860","full_name":"Rueda Sanchez, Alfredo R","id":"3B82B0F8-F248-11E8-B48F-1D18A9856A87","first_name":"Alfredo R"},{"first_name":"Rishabh","id":"47D26E34-F248-11E8-B48F-1D18A9856A87","last_name":"Sahu","orcid":"0000-0001-6264-2162","full_name":"Sahu, Rishabh"},{"last_name":"Wulf","full_name":"Wulf, Matthias","orcid":"0000-0001-6613-1378","id":"45598606-F248-11E8-B48F-1D18A9856A87","first_name":"Matthias"},{"first_name":"Georg M","id":"3770C838-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1397-7876","full_name":"Arnold, Georg M","last_name":"Arnold"},{"first_name":"Harald G.L.","full_name":"Schwefel, Harald G.L.","last_name":"Schwefel"},{"orcid":"0000-0001-8112-028X","full_name":"Fink, Johannes M","last_name":"Fink","first_name":"Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87"}],"article_processing_charge":"No","external_id":{"isi":["000674680100001"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Hease WJ, Rueda Sanchez AR, Sahu R, Wulf M, Arnold GM, Schwefel HGL, Fink JM. 2020.

Our review covers the leading approaches to achieving such transduction, with an emphasis on those based on atomic ensembles, opto-electro-mechanics, and electro-optics. We briefly discuss relevant metrics from the point of view of different applications, as well as challenges for the future."}],"month":"03","intvolume":" 5","scopus_import":"1"},{"_id":"13071","status":"public","type":"research_data_reference","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"ddc":["530"],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-08-24T11:16:35Z","citation":{"mla":"Hease, William J., et al.

Optical photons, unlike microwave photons, can be transmitted by fiber, making them suitable for long distance quantum communication. Moreover, the optical domain offers access to a large set of very well‐developed quantum optical tools, such as highly efficient single‐photon detectors and long‐lived quantum memories. For a high fidelity microwave to optical transducer, efficient conversion at single photon level and low added noise is needed. Currently, the most promising approaches to build such systems are based on second‐order nonlinear phenomena such as optomechanical and electro‐optic interactions. Alternative approaches, although not yet as efficient, include magneto‐optical coupling and schemes based on isolated quantum systems like atoms, ions, or quantum dots. Herein, the necessary theoretical foundations for the most important microwave‐to‐optical conversion experiments are provided, their implementations are described, and the current limitations and future prospects are discussed.","lang":"eng"}],"file_date_updated":"2021-03-02T12:30:03Z","department":[{"_id":"JoFi"}],"ddc":["530"],"date_updated":"2023-08-24T13:53:02Z","status":"public","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc/4.0/legalcode","image":"/images/cc_by_nc.png","name":"Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0)","short":"CC BY-NC (4.0)"},"type":"journal_article","article_type":"original","_id":"9195"},{"year":"2020","isi":1,"has_accepted_license":"1","publication":"Physical Review Applied","day":"29","date_created":"2020-11-15T23:01:17Z","doi":"10.1103/PhysRevApplied.14.044055","date_published":"2020-10-29T00:00:00Z","acknowledgement":"The authors acknowledge the support from I.

These circuit elements have a characteristic impedance exceeding the resistance quantum RQ ≈ 6.45 kΩ which leads to a suppression of ground state charge fluctuations. Applications include the realization of hardware protected qubits for fault tolerant quantum computing, improved coupling to small dipole moment objects and defining a new quantum metrology standard for the ampere. In this work we refute the widespread notion that superinductors can only be implemented based on kinetic inductance, i.e. using disordered superconductors or Josephson junction arrays. We present modeling, fabrication and characterization of 104 planar aluminum coil resonators with a characteristic impedance up to 30.9 kΩ at 5.6 GHz and a capacitance down to ≤ 1 fF, with lowloss and a power handling reaching 108 intra-cavity photons. Geometric superinductors are free of uncontrolled tunneling events and offer high reproducibility, linearity and the ability to couple magnetically - properties that significantly broaden the scope of future quantum circuits.

A key challenge in this field is obtaining strong coupling between motion and electromagnetic fields without adding additional decoherence. Here we present an electromechanical transducer that integrates a high-frequency (0.42 GHz) hypersonic phononic crystal with a superconducting microwave circuit. The use of a phononic bandgap crystal enables quantum-level transduction of hypersonic mechanical motion and concurrently eliminates decoherence caused by acoustic radiation.

There, complicated electric and magnetic fields varying over subwavelength scales are generally present, which results in photonic phenomena such as extraordinary optical momentum, superchiral fields, and a complex spatial evolution of optical singularities. An understanding of such phenomena requires nanoscale measurements of the complete optical field vector. Although the sensitivity of near- field scanning optical microscopy to the complete electromagnetic field was recently demonstrated, a separation of different components required a priori knowledge of the sample. Here, we introduce a robust algorithm that can disentangle all six electric and magnetic field components from a single near-field measurement without any numerical modeling of the structure. As examples, we unravel the fields of two prototypical nanophotonic structures: a photonic crystal waveguide and a plasmonic nanowire.

Higher bandwidths require higher total optical power, but the power sent into the fibre is limited by optical nonlinearities within the fibre, and energy consumption by the light sources starts to become a substantial cost factor1. Optical frequency combs have been suggested to remedy this problem by generating numerous discrete, equidistant laser lines within a monolithic device; however, at present their stability and coherence allow them to operate only within small parameter ranges2,3,4. Here we show that a broadband frequency comb realized through the electro-optic effect within a high-quality whispering-gallery-mode resonator can operate at low microwave and optical powers. Unlike the usual third-order Kerr nonlinear optical frequency combs, our combs rely on the second-order nonlinear effect, which is much more efficient. Our result uses a fixed microwave signal that is mixed with an optical-pump signal to generate a coherent frequency comb with a precisely determined carrier separation. The resonant enhancement enables us to work with microwave powers that are three orders of magnitude lower than those in commercially available devices. We emphasize the practical relevance of our results to high rates of data communication. To circumvent the limitations imposed by nonlinear effects in optical communication fibres, one has to solve two problems: to provide a compact and fully integrated, yet high-quality and coherent, frequency comb generator; and to calculate nonlinear signal propagation in real time5. We report a solution to the first problem.","lang":"eng"}],"department":[{"_id":"JoFi"}],"date_updated":"2023-08-25T10:15:25Z","status":"public","type":"journal_article","_id":"6348"},{"department":[{"_id":"JoFi"}],"date_updated":"2023-08-28T12:29:56Z","status":"public","type":"journal_article","_id":"6609","volume":570,"ec_funded":1,"language":[{"iso":"eng"}],"publication_status":"published","month":"06","intvolume":" 570","scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1809.05865"}],"oa_version":"Preprint","abstract":[{"text":"Mechanical systems facilitate the development of a hybrid quantum technology comprising electrical, optical, atomic and acoustic degrees of freedom1, and entanglement is essential to realize quantum-enabled devices. Continuous-variable entangled fields—known as Einstein–Podolsky–Rosen (EPR) states—are spatially separated two-mode squeezed states that can be used for quantum teleportation and quantum communication2. In the optical domain, EPR states are typically generated using nondegenerate optical amplifiers3, and at microwave frequencies Josephson circuits can serve as a nonlinear medium4,5,6. An outstanding goal is to deterministically generate and distribute entangled states with a mechanical oscillator, which requires a carefully arranged balance between excitation, cooling and dissipation in an ultralow noise environment. Here we observe stationary emission of path-entangled microwave radiation from a parametrically driven 30-micrometre-long silicon nanostring oscillator, squeezing the joint field operators of two thermal modes by 3.40 decibels below the vacuum level. The motion of this micromechanical system correlates up to 50 photons per second per hertz, giving rise to a quantum discord that is robust with respect to microwave noise7. Such generalized quantum correlations of separable states are important for quantum-enhanced detection8 and provide direct evidence of the non-classical nature of the mechanical oscillator without directly measuring its state9. This noninvasive measurement scheme allows to infer information about otherwise inaccessible objects, with potential implications for sensing, open-system dynamics and fundamental tests of quantum gravity. In the future, similar on-chip devices could be used to entangle subsystems on very different energy scales, such as microwave and optical photons.","lang":"eng"}],"acknowledged_ssus":[{"_id":"NanoFab"}],"title":"Stationary entangled radiation from micromechanical motion","author":[{"last_name":"Barzanjeh","full_name":"Barzanjeh, Shabir","orcid":"0000-0003-0415-1423","id":"2D25E1F6-F248-11E8-B48F-1D18A9856A87","first_name":"Shabir"},{"full_name":"Redchenko, Elena","last_name":"Redchenko","first_name":"Elena","id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87"},{"id":"3F920B30-F248-11E8-B48F-1D18A9856A87","first_name":"Matilda","orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","last_name":"Peruzzo"},{"last_name":"Wulf","orcid":"0000-0001-6613-1378","full_name":"Wulf, Matthias","first_name":"Matthias","id":"45598606-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lewis, Dylan","last_name":"Lewis","first_name":"Dylan"},{"id":"3770C838-F248-11E8-B48F-1D18A9856A87","first_name":"Georg M","last_name":"Arnold","orcid":"0000-0003-1397-7876","full_name":"Arnold, Georg M"},{"first_name":"Johannes M","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X"}],"article_processing_charge":"No","external_id":{"isi":["000472860000042"],"arxiv":["1809.05865"]},"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","citation":{"ista":"Barzanjeh S, Redchenko E, Peruzzo M, Wulf M, Lewis D, Arnold GM, Fink JM. 2019.

The device is based on a single crystal whispering gallery mode resonator integrated into a 3D-microwave cavity. The specific design relies on a new combination of thin-film technology and conventional machining that is optimized for the lowest dissipation rates in the microwave, optical, and mechanical domains. We extract important device properties from finite-element simulations and predict continuous variable entanglement generation rates on the order of a Mebit/s for optical pump powers of only a few tens of microwatts. We compare the quantum state transfer fidelities of coherent, squeezed, and non-Gaussian cat states for both teleportation and direct conversion protocols under realistic conditions. Combining the unique capabilities of circuit quantum electrodynamics with the resilience of fiber optic communication could facilitate long-distance solid-state qubit networks, new methods for quantum signal synthesis, quantum key distribution, and quantum enhanced detection, as well as more power-efficient classical sensing and modulation.","lang":"eng"}],"oa_version":"Published Version","scopus_import":"1","month":"12","intvolume":" 5","publication_identifier":{"issn":["2056-6387"]},"publication_status":"published","file":[{"content_type":"application/pdf","relation":"main_file","access_level":"open_access","file_id":"7157","checksum":"13e0ea1d4f9b5f5710780d9473364f58","file_size":1580132,"date_updated":"2020-07-14T12:47:50Z","creator":"dernst","file_name":"2019_NPJ_Rueda.pdf","date_created":"2019-12-09T08:25:06Z"}],"language":[{"iso":"eng"}],"volume":5,"ec_funded":1,"article_number":"108","project":[{"grant_number":"758053","name":"A Fiber Optic Transceiver for Superconducting Qubits","call_identifier":"H2020","_id":"26336814-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","_id":"258047B6-B435-11E9-9278-68D0E5697425","name":"Microwave-to-Optical Quantum Link: Quantum Teleportation and Quantum Illumination with cavity Optomechanics SUPEREOM","grant_number":"707438"},{"grant_number":"732894","name":"Hybrid Optomechanical Technologies","call_identifier":"H2020","_id":"257EB838-B435-11E9-9278-68D0E5697425"},{"_id":"26927A52-B435-11E9-9278-68D0E5697425","call_identifier":"FWF","grant_number":"F07105","name":"Integrating superconducting quantum circuits"}],"citation":{"short":"A.R.
