A persistent-current-biased and current-actuated switch for superconducting circuits
Ziyi Zhao, Eva Gurra, Michael R. Vissers +1
Broadband and low-loss superconducting switches can facilitate large-scale quantum information processors and cryogenic detectors by dynamically reconfiguring the connectivity of t…

Can slow recombination in ordered superconductors explain the excess quasiparticle population?
Eva Gurra, Douglas A. Bennett, Shannon M. Duff +2
An excess density of quasiparticles is widely observed in superconducting films. This excess causes performance degradation in a variety of superconducting devices, including decoh…

Integrating planar circuits with superconducting 3D microwave cavities using tunable low-loss couplers
Ziyi Zhao, Eva Gurra, Eric I. Rosenthal +3
We design and test a low-loss interface between superconducting 3-dimensional microwave cavities and 2-dimensional circuits, where the coupling rate is highly tunable. This interfa…
