Stationary optomechanical entanglement between a mechanical oscillator and its measurement apparatus
C. Gut, K. Winkler, J. Hoelscher-Obermaier +9
We provide an argument to infer stationary entanglement between light and a mechanical oscillator based on continuous measurement of light only. We propose an experimentally realiz…
Motional Quantum Ground State of a Levitated Nanoparticle from Room Temperature
Uroš Delić, Manuel Reisenbauer, Kahan Dare +4
We report quantum ground state cooling of a levitated nanoparticle in a room temperature environment. Using coherent scattering into an optical cavity we cool the center of mass mo…
Information Content of the Gravitational Field of a Quantum Superposition
Alessio Belenchia, Robert M. Wald, Flaminia Giacomini +3
When a massive quantum body is put into a spatial superposition, it is of interest to consider the quantum aspects of the gravitational field sourced by the body. We argue that in…
Levitated cavity optomechanics in high vacuum
Uroš Delić, David Grass, Manuel Reisenbauer +4
We report dispersive coupling of an optically trapped silica nanoparticle (nm diameter) to the field of a driven Fabry-Perot cavity in high vacuum (mbar).…
