Quantum-Limited Amplification and Parametric Instability in the Reversed Dissipation Regime of Cavity Optomechanics

Cavity optomechanical phenomena, such as cooling, amplification, or optomechanically induced transparency, emerge due to a strong imbalance in the dissipation rates of the parametrically coupled electromagnetic and mechanical resonators. Here we analyze th ...

Heralded Single-Phonon Preparation, Storage, and Readout in Cavity Optomechanics

Nicolas Gisin, Christophe Marcel Georges Galland, Tobias Kippenberg, Nicolas Piro Mastracchio

We show how to use the radiation pressure optomechanical coupling between a mechanical oscillator and an optical cavity field to generate in a heralded way a single quantum of mechanical motion (a Fock state). Starting with the oscillator close to its grou ...
