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…
Identifying Materials-Level Sources of Performance Variation in Superconducting Transmon Qubits
Akshay A. Murthy, Mustafa Bal, Michael J. Bedzyk +46
The Superconducting Materials and Systems (SQMS) Center, a DOE National Quantum Information Science Research Center, has conducted a comprehensive and coordinated study using super…
Mapping the topological proximity-induced gap of multiterminal Josephson junctions
Maxwell Wisne, Yanpei Deng, Markus Lilja +2
Multiterminal Josephson junctions (MTJJs), devices in which a normal metal is in contact with three or more superconducting leads, have been proposed as artificial analogs of topol…
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…
