Non-linearity in the system of quasiparticles of a superconducting resonator
M. Vignati, C. Bellenghi, L. Cardani +3
We observed a strong non-linearity in the system of quasiparticles of a superconducting aluminum resonator, due to the Cooper-pair breaking from the absorbed readout power. We obse…
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…
Phonon traps reduce the quasiparticle density in superconducting circuits
Fabio Henriques, Francesco Valenti, Thibault Charpentier +14
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 kineti…
