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"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"10924","ddc":["530"],"title":"Quantum-enabled operation of a microwave-optical interface","status":"public","intvolume":" 13","oa_version":"Published Version","file":[{"access_level":"open_access","file_name":"2022_NatureCommunications_Sahu.pdf","file_size":1167492,"content_type":"application/pdf","creator":"dernst","relation":"main_file","file_id":"10929","checksum":"7c5176db7b8e2ed18a4e0c5aca70a72c","success":1,"date_created":"2022-03-28T08:02:12Z","date_updated":"2022-03-28T08:02:12Z"}],"month":"03","publication_identifier":{"eissn":["20411723"]},"external_id":{"isi":["000767892300013"],"arxiv":["2107.08303"]},"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"quality_controlled":"1","isi":1,"project":[{"name":"A Fiber Optic Transceiver for Superconducting Qubits","call_identifier":"H2020","_id":"26336814-B435-11E9-9278-68D0E5697425","grant_number":"758053"},{"call_identifier":"H2020","name":"Quantum Local Area Networks with Superconducting Qubits","grant_number":"899354","_id":"9B868D20-BA93-11EA-9121-9846C619BF3A"},{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"call_identifier":"FWF","name":"Integrating superconducting quantum circuits","grant_number":"F07105","_id":"26927A52-B435-11E9-9278-68D0E5697425"},{"_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E","grant_number":"862644","call_identifier":"H2020","name":"Quantum readout techniques and technologies"}],"doi":"10.1038/s41467-022-28924-2","acknowledged_ssus":[{"_id":"M-Shop"}],"language":[{"iso":"eng"}],"article_number":"1276","file_date_updated":"2022-03-28T08:02:12Z","ec_funded":1,"license":"https://creativecommons.org/licenses/by/4.0/","acknowledgement":"The authors thank S.

We investigate the effect of in-plane magnetic fields up to 1 T on the spectrum and coherence times of thin-film three-dimensional aluminum transmons. 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"}],"type":"journal_article","date_published":"2022-04-13T00:00:00Z","article_type":"original","citation":{"mla":"Qiu, Liu, et al. “Dissipative Quantum Feedback in Measurements Using a Parametrically Coupled Microcavity.” PRX Quantum, vol. 3, no. 2, 020309, American Physical Society, 2022, doi:10.1103/PRXQuantum.3.020309.","short":"L.

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. We are proud to present a collection that touches on a wide range of technologies including superconductors,7–13,21 semiconductors,15–17,19 and individual atomic qubits.18\r\n","lang":"eng"}],"issue":"19","type":"journal_article","date_published":"2022-05-12T00:00:00Z","publication":"Applied Physics Letters","citation":{"ama":"Sigillito AJ, Covey JP, Fink JM, Petersson K, Preble S.
