Supercurrent tuning of the Josephson coupling energy
Maxwell Wisne, Venkat Chandrasekhar
The ability to non-dissipatively tune the Josephson coupling energy of Josephson junctions is a useful tool in frequency-tunable qubits. This is typically done by threading magneti…

Transport signatures of phase fluctuations in superconducting qubits
Maxwell Wisne, Yanpei Deng, Hilal Cansizoglu +3
Josephson junctions supply the nonlinear inductance element in superconducting qubits. In the widely used transmon configuration, where the junction is shunted by a large capacitor…
