Macroscopic mechanical oscillators at the quantum limit using optomechanical cooling
arXiv:quant-ph/0211102 · doi:10.1364/JOSAB.20.001054
Abstract
We discuss how the optomechanical coupling provided by radiation pressure can be used to cool macroscopic collective degrees of freedom, as vibrational modes of movable mirrors. Cooling is achieved using a phase-sensitive feedback-loop which effectively overdamps the mirrors motion without increasing the thermal noise. Feedback results able to bring macroscopic objects down to the quantum limit. In particular, it is possible to achieve squeezing and entanglement.
