Loss mechanisms in superconducting thin film microwave resonators
Jan Goetz, Frank Deppe, Max Haeberlein +10
We present a systematic analysis of the internal losses of superconducting coplanar waveguide microwave resonators based on niobium thin films on silicon substrates. In particular,…
Tunable coupling of transmission-line microwave resonators mediated by an rf SQUID
F. Wulschner, J. Goetz, F. R. Koessel +18
We realize tunable coupling between two superconducting transmission line resonators. The coupling is mediated by a non-hysteretic rf SQUID acting as a flux-tunable mutual inductan…
High cooperativity coupling between a phosphorus donor spin ensemble and a superconducting microwave resonator
Christoph W. Zollitsch, Kai Mueller, David P. Franke +4
We investigate the coupling of an ensemble of phosphorus donors in an isotopically purified Si host lattice interacting with a superconducting coplanar waveguide resonator.…
