Remote sensing of a levitated superconductor with a flux-tunable microwave cavity
Philip Schmidt, Remi Claessen, Gerard Higgins +9
We present a cavity-electromechanical system comprising a superconducting quantum interference device which is embedded in a microwave resonator and coupled via a pick-up loop to a…
