Optical Interferometric Readout of a Magnetically Levitated Superconducting Microsphere
J. J. Hansen, S. Minniberger, D. Ilk +8
We probe the motion of a 6 magnetically levitated superconducting microsphere using optical interferometry at 3 K, achieving a resolution better than 1 , and us…
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…
High-Q magnetic levitation and control of superconducting microspheres at millikelvin temperatures
Joachim Hofer, Rudolf Gross, Gerard Higgins +11
We report the levitation of a superconducting lead-tin sphere with 100 micrometer diameter (corresponding to a mass of 5.6 micrograms) in a static magnetic trap formed by two coils…
Cooling-by-measurement and mechanical state tomography via pulsed optomechanics
M. R. Vanner, J. Hofer, G. D. Cole +1
Observing a physical quantity without disturbing it is a key capability for the control of individual quantum systems. Such back-action-evading or quantum-non-demolition measuremen…
