Moreover, thanks to their high impedance, quantum buses made of such materials enable large zero-point fluctuations of the voltage, boosting the coupling rates to spin and charge qubits. However, fully exploiting the potential of disordered or granular superconductors is challenging, as their inductance and, therefore, impedance at high values are difficult to control. Here, we report a reproducible fabrication of granular aluminium resonators by developing a wireless ohmmeter, which allows in situ measurements during film deposition and, therefore, control of the kinetic inductance of granular aluminium films. Reproducible fabrication of circuits with impedances (inductances) exceeding 13 kΩ (1 nH per square) is now possible. By integrating a 7.9 kΩ resonator with a germanium double quantum dot, we demonstrate strong charge-photon coupling with a rate of gc/2π = 566 ± 2 MHz. This broadly applicable method opens the path for novel qubits and high-fidelity, long-distance two-qubit gates.","lang":"eng"}],"ddc":["530"],"oa":1,"file_date_updated":"2025-03-17T10:53:32Z","related_material":{"record":[{"id":"18144","relation":"earlier_version","status":"public"},{"status":"public","relation":"research_data","id":"18886"}]},"intvolume":"        16","doi":"10.1038/s41467-025-57252-4","date_created":"2025-03-16T23:01:23Z","citation":{"apa":"Janik, M., Roux, K.

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.","lang":"eng"}],"file_date_updated":"2022-01-18T11:29:33Z","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","file":[{"relation":"main_file","file_id":"10641","creator":"cchlebak","date_updated":"2022-01-18T11:29:33Z","date_created":"2022-01-18T11:29:33Z","access_level":"open_access","content_type":"application/pdf","checksum":"36eb41ea43d8ca22b0efab12419e4eb2","file_size":4247422,"success":1,"file_name":"2021_PRXQuantum_Peruzzo.pdf"}],"date_published":"2021-11-24T00:00:00Z","external_id":{"arxiv":["2106.05882"],"isi":["000723015100001"]},"author":[{"last_name":"Peruzzo","id":"3F920B30-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3415-4628","full_name":"Peruzzo, Matilda","first_name":"Matilda"},{"last_name":"Hassani","id":"2AED110C-F248-11E8-B48F-1D18A9856A87","full_name":"Hassani, Farid","orcid":"0000-0001-6937-5773","first_name":"Farid"},{"first_name":"Gregory","full_name":"Szep, Gregory","last_name":"Szep"},{"full_name":"Trioni, Andrea","id":"42F71B44-F248-11E8-B48F-1D18A9856A87","last_name":"Trioni","first_name":"Andrea"},{"first_name":"Elena","last_name":"Redchenko","id":"2C21D6E8-F248-11E8-B48F-1D18A9856A87","full_name":"Redchenko, Elena"},{"orcid":"0009-0005-0878-3032","full_name":"Zemlicka, Martin","id":"2DCF8DE6-F248-11E8-B48F-1D18A9856A87","last_name":"Zemlicka","first_name":"Martin"},{"full_name":"Fink, Johannes M","orcid":"0000-0001-8112-028X","id":"4B591CBA-F248-11E8-B48F-1D18A9856A87","last_name":"Fink","first_name":"Johannes M"}],"volume":2,"acknowledgement":"We thank W.
