Abstract
Cavity-enhanced interferometry is used to resolve the displacement of a 4.3 MHz nanobeam oscillator with an imprecision 40 dB below that at the standard quantum limit. Employing this measurement as an error signal, radiation pressure is used to feedback cool the oscillator to 5.3 mechanical quanta.
