Abstract

Quantum mechanics sets a limit on continuous position measurement of a harmonic oscillator, due to quantum backaction from quantum fluctuations in the measurement field. We demonstrate continuous optical two-tone backaction-evading measurement of a mechanical mode of a photonic crystal nanobeam.
