Abstract

A position sensor is demonstrated that is capable of resolving the zero-point motion of a nanomechanical oscillator in the timescale of its thermal decoherence; it achieves an imprecision that is four orders of magnitude below that at the standard quantum limit and is used to feedback-cool the oscillator to a mean photon number of five.
