Electronic confinement of surface states in a topological insulator nanowire
Ruchi Saxena, Eytan Grosfeld, Sebastian E de Graaf +4
We analyze the confinement of electronic surface states in a model of a topological insulator nanowire. Spin-momentum locking in the surface states reduces unwanted backscattering…
Integration of topological insulator Josephson junctions in superconducting qubit circuits
Tobias W. Schmitt, Malcolm R. Connolly, Michael Schleenvoigt +16
The integration of semiconductor Josephson junctions (JJs) in superconducting quantum circuits provides a versatile platform for hybrid qubits and offers a powerful way to probe ex…
High-cooperativity coupling of a rare-earth spin ensemble to a superconducting resonator using yttrium orthosilicate as a substrate
Gavin Dold, Christoph W. Zollitsch, James O'Sullivan +6
Yttrium orthosilicate (YSiO, or YSO) has proved to be a convenient host for rare-earth ions used in demonstrations of microwave quantum memories and optical memories with m…
Slow noise processes in superconducting resonators
Jonathan Burnett, Tobias Lindström, Mark Oxborrow +4
Slow noise processes, with characteristic timescales ~1s, have been studied in planar superconducting resonators. A frequency locked loop is employed to track deviations of the res…
Magnetic field tuning of coplanar waveguide resonators
J. E. Healey, T. Lindstrom, M. S. Colclough +2
We describe measurements on microwave coplanar resonators designed for quantum bit experiments. Resonators have been patterned onto sapphire and silicon substrates, and quality fac…
