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 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":{"chicago":"Hassani, Farid, Matilda Peruzzo, Lucky Kapoor, Andrea Trioni, Martin Zemlicka, and Johannes M Fink. “Inductively Shunted Transmons Exhibit Noise Insensitive Plasmon States and a Fluxon Decay Exceeding 3 Hours.” Nature Communications.

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"}],"oa_version":"Published Version","alternative_title":["Bluefors Blog"],"quality_controlled":"1","publisher":"Bluefors Oy","main_file_link":[{"open_access":"1","url":"https://bluefors.com/blog/application-note-qubit-energy-relaxation-statistics-bluefors-quantum-measurement-system/"}],"oa":1,"place":"Helsinki, Finland","month":"06","year":"2021","publication_status":"published","day":"03","language":[{"iso":"eng"}],"page":"8","date_published":"2021-06-03T00:00:00Z","date_created":"2022-01-19T08:41:14Z"},{"_id":"10644","type":"other_academic_publication","status":"public","keyword":["Application note"],"citation":{"chicago":"Lake, Russell, Slawomir Simbierowicz, Philip Krantz, Farid Hassani, and Johannes M Fink.

Our motivation is twofold. First, we provide pre-qualification data that the Bluefors cryostat, including filtering and wiring, can support long-lived qubits. Second, we demonstrate that the Keysight system (controlled using Labber) provides a straightforward solution to perform these characterization measurements. This document is intended as a brief guide for starting an experimental platform for testing superconducting qubits. The setup described here is an immediate jumping off point for a suite of applications including testing quantum logical gates, quantum optics with microwaves, or even using the qubit itself as a sensitive probe of local electromagnetic fields. Qubit measurements rely on high performance of both the physical sample environment and the measurement electronics. An overview of the cryogenic system is shown in Figure 1, and an overview of the integration between the electronics and cryostat (including wiring details) is shown in Figure 2."}],"oa_version":"Published Version","quality_controlled":"1","publisher":"Bluefors Oy","alternative_title":["Bluefors Blog"],"oa":1,"main_file_link":[{"url":"https://bluefors.com/blog/integrated-quantum-measurement-system/","open_access":"1"}],"month":"04","place":"Helsinki, Finland","publication_status":"published","year":"2021","day":"20","language":[{"iso":"eng"}],"page":"9","date_published":"2021-04-20T00:00:00Z","date_created":"2022-01-19T08:29:57Z"},{"day":"22","year":"2021","date_created":"2023-05-23T13:42:27Z","related_material":{"record":[{"status":"public","id":"9928","relation":"used_in_publication"}]},"date_published":"2021-10-22T00:00:00Z","doi":"10.5281/ZENODO.5592103","oa_version":"Published Version","abstract":[{"text":"This dataset comprises all data shown in the figures of the submitted article \"Geometric superinductance qubits: Controlling phase delocalization across a single Josephson junction\".

In one, the inductor is replaced by a nonlinear Josephson junction to realize the widely used charge qubits with a compact phase variable and a discrete charge wave function. In the other, the junction is added in parallel, which gives rise to an extended phase variable, continuous wave functions, and a rich energy-level structure due to the loop topology. 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 use of a geometric inductor results in high reproducibility of the inductive energy as guaranteed by top-down lithography—a key ingredient for intrinsically protected superconducting qubits."}],"acknowledged_ssus":[{"_id":"NanoFab"},{"_id":"M-Shop"}],"file_date_updated":"2022-01-18T11:29:33Z","department":[{"_id":"JoFi"},{"_id":"NanoFab"},{"_id":"M-Shop"}],"ddc":["530"],"date_updated":"2023-09-07T13:31:22Z","keyword":["quantum physics","mesoscale and nanoscale physics"],"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","_id":"9928","date_created":"2021-08-17T08:14:18Z","doi":"10.1103/PRXQuantum.2.040341","date_published":"2021-11-24T00:00:00Z","page":"040341","publication":"PRX Quantum","day":"24","year":"2021","has_accepted_license":"1","isi":1,"oa":1,"quality_controlled":"1","publisher":"American Physical Society","acknowledgement":"We thank W.

The latter could be provided by superconducting circuits but existing solutions to interface the microwave and optical domains lack either scalability or efficiency, and in most cases the conversion noise is not known. 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"}],"acknowledged_ssus":[{"_id":"NanoFab"}],"oa_version":"Published Version","intvolume":" 11","month":"09","publication_status":"published","publication_identifier":{"issn":["2041-1723"]},"language":[{"iso":"eng"}],"file":[{"file_name":"2020_NatureComm_Arnold.pdf","date_created":"2020-09-18T13:02:37Z","file_size":1002818,"date_updated":"2020-09-18T13:02:37Z","creator":"dernst","success":1,"checksum":"88f92544889eb18bb38e25629a422a86","file_id":"8530","content_type":"application/pdf","relation":"main_file","access_level":"open_access"}],"ec_funded":1,"volume":11,"related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1038/s41467-020-18912-9"},{"description":"News on IST Homepage","url":"https://ist.ac.at/en/news/how-to-transport-microwave-quantum-information-via-optical-fiber/","relation":"press_release"}],"record":[{"id":"13056","status":"public","relation":"research_data"}]},"article_number":"4460","project":[{"grant_number":"732894","name":"Hybrid Optomechanical Technologies","call_identifier":"H2020","_id":"257EB838-B435-11E9-9278-68D0E5697425"},{"call_identifier":"H2020","_id":"26336814-B435-11E9-9278-68D0E5697425","name":"A Fiber Optic Transceiver for Superconducting Qubits","grant_number":"758053"},{"name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425"},{"_id":"237CBA6C-32DE-11EA-91FC-C7463DDC885E","call_identifier":"H2020","grant_number":"862644","name":"Quantum readout techniques and technologies"},{"name":"Coherent on-chip conversion of superconducting qubit signals from microwaves to optical frequencies","_id":"2671EB66-B435-11E9-9278-68D0E5697425"}],"citation":{"ista":"Arnold GM, Wulf M, Barzanjeh S, Redchenko E, Rueda Sanchez AR, Hease WJ, Hassani F, Fink JM. 2020.

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.
