Gate-dependent offset charge shifts and anharmonicity in gatemon qubits in the weak tunneling regime

Utkan Güngördü, Rusko Ruskov, Silas Hoffman +3

Gatemon qubits are based on a superconductor-quantum dot-superconductor (S-QD-S) junction which enables in situ electrostatic tuning via a gate electrode. For a single-channel QD t…
