Gate-tunable kinetic inductance in proximitized nanowires
Lukas Johannes Splitthoff, Arno Bargerbos, Lukas Grünhaupt +6
We report the detection of a gate-tunable kinetic inductance in a hybrid InAs/Al nanowire. For this purpose, we have embedded the nanowire into a quarter-wave coplanar waveguide re…
Reducing the impact of radioactivity on quantum circuits in a deep-underground facility
Laura Cardani, Francesco Valenti, Nicola Casali +20
As quantum coherence times of superconducting circuits have increased from nanoseconds to hundreds of microseconds, they are currently one of the leading platforms for quantum info…
Microscopic charging and in-gap states in superconducting granular aluminum
Fang Yang, Tim Storbeck, Thomas Gozlinski +3
Following the emergence of superconducting granular aluminum (grAl) as a material for high-impedance quantum circuits, future development hinges on a microscopic understanding of i…
Interplay between kinetic inductance, non-linearity and quasiparticle dynamics in granular aluminum MKIDs
Francesco Valenti, Fábio Henriques, Gianluigi Catelani +13
Microwave kinetic inductance detectors (MKIDs) are thin film, cryogenic, superconducting resonators. Incident Cooper pair-breaking radiation increases their kinetic inductance, the…
Circuit Quantum Electrodynamics of Granular Aluminum Resonators
N. Maleeva, L. Grünhaupt, T. Klein +12
The introduction of crystalline defects or dopants can give rise to so-called "dirty superconductors", characterized by reduced coherence length and quasiparticle mean free path. I…
Quasiparticle dynamics in granular aluminum close to the superconductor to insulator transition
Lukas Grünhaupt, Nataliya Maleeva, Sebastian T. Skacel +7
Superconducting high kinetic inductance elements constitute a valuable resource for quantum circuit design and millimeter-wave detection. Granular aluminum (GrAl) in the supercondu…
Bistability in a Mesoscopic Josephson Junction Array Resonator
P. R. Muppalla, O. Gargiulo, S. I. Mirzaei +5
We present an experimental investigation of stochastic switching of a bistable Josephson junctions array resonator with a resonance frequency in the GHz range. As the device is in…
