Observation of coherent flux-charge interaction in a gate-tunable fluxonium
Brian D. Isakov, Shikhar Singh, Adrian Parra-Rodriguez +7
Interactions that mix conjugate variables, such as the flux through a circuit element and the charge across it, lie outside the reach of the elementary couplings of superconducting…

Junction-Intrinsic Dissipation in Hybrid Superconductor-Semiconductor Gatemon Qubits
Zhenhai Sun, David Feldstein-Bofill, Ksenia Shagalov +10
Superconducting transmon qubits based on hybrid superconductor-semiconductor Josephson junctions (gatemons) offer gate tunability, but their relaxation times remain well below thos…
