In situ calibration of microwave attenuation and gain using a cryogenic on-chip attenuator
Thomas Descamps, Linus Andersson, Vittorio Buccheri +3
Accurate in situ calibration of microwave attenuation and amplification-chain noise is essential for superconducting quantum circuits. We demonstrate a compact, self-calibrating cr…

Approaching the ultrastrong coupling regime between an Andreev level and a microwave resonator
O. O. Shvetsov, A. Khola, V. Buccheri +5
Josephson junctions formed in semiconductor nanowires host Andreev bound states and serve as a physical platform to realize Andreev qubits tuned by electrostatic gating. With the A…

Microwave dynamics of gated Al/InAs superconducting nanowires
Vittorio Buccheri, François Joint, Kazi Rafsamjani Amin +9
Several experiments have recently reported on gate-tunable superconducting properties in metallic devices, holding promise for the realization of cryogenic switches, tunable resona…
