Superconducting levitation and control of a high-reflectivity micromirror
Philipp Koller, Jannek J. Hansen, David Walcher +9
We introduce a method to suspend an optical micromirror, with a total mass of \SI{30}{\micro\gram}, using superconducting magnetic levitation. The micromirror is formed on a silico…
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…
Universality of stationary entanglement in an optomechanical system driven by non-Markovian noise and squeezed light
Su Direkci, Klemens Winkler, Corentin Gut +2
Optomechanical systems subjected to environmental noise give rise to rich physical phenomena. We investigate entanglement between a mechanical oscillator and the reflected coherent…
Characterizing stationary optomechanical entanglement in the presence of non-Markovian noise
Su Direkci, Klemens Winkler, Corentin Gut +2
We study an optomechanical system, where a mechanical oscillator interacts with a Gaussian input optical field. In the linearized picture, we analytically prove that if the input l…
Steady-state entanglement of interacting masses in free space through optimal feedback control
Klemens Winkler, Anton V. Zasedatelev, Benjamin A. Stickler +3
We develop a feedback strategy based on optimal quantum feedback control for Gaussian systems to maximise the likelihood of steady-state entanglement detection between two directly…
Nonequilibrium entanglement between levitated masses under optimal control
Alexander N. Poddubny, Klemens Winkler, Benjamin A. Stickler +3
We present a protocol that maximizes unconditional entanglement generation between two masses interacting directly through potential. The protocol combines optimal quantu…
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…
