Evidence for unexpectedly low quasiparticle generation rates across Josephson junctions of driven superconducting qubits
Byoung-moo Ann, Sang-Jun Choi, Hee Chul Park +6
Recent studies find that even drives far below the superconducting gap frequency may cause drive-induced quasiparticle generation (QPG) across Josephson junctions (JJs) of supercon…

Entangling interactions between artificial atoms mediated by a multimode left-handed superconducting ring resonator
T. McBroom-Carroll, A. Schlabes, X. Xu +6
Superconducting metamaterial transmission lines implemented with lumped circuit elements can exhibit left-handed dispersion, where the group and phase velocity have opposite sign,…
