Published in 2019 at "Applied Physics Letters"

DOI: 10.1063/1.5124967

Abstract: Out of equilibrium quasiparticles (QPs) are one of the main sources of decoherence in superconducting quantum circuits, and are particularly detrimental in devices with high kinetic inductance, such as high impedance resonators, qubits, and detectors.… read more here.

Published in 2023 at "Applied Physics Letters"

DOI: 10.1063/5.0148250

Abstract: We present electrical characterization data of sputtered Nb/a-Si/Nb Josephson junctions (JJs) for high-speed and high-density superconducting circuits. Junctions were studied with critical current densities (Jc) ranging from 0.01 to 3 mA/μm2 at 4 K. For junctions deposited… read more here.
