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…

Controlled Parity of Cooper Pair Tunneling in a Hybrid Superconducting Qubit
David Feldstein-Bofill, Leo Uhre Jakobsen, Ksenia Shagalov +9
Superconducting quantum circuits derive their nonlinearity from the Josephson energy-phase relation. Besides the fundamental term, this relation can also contain higher Fou…
