Quantum Light for Quantum Mechanics

Squeezed states of light are known to enhance mechanical displacement sensing by suppressing the “photon counting noise" that limits the measurement's noise floor. On the other hand, recent experiments in cavity optomechanics have reached measurement regimes where an interrogating light field exerts radiation pressure noise on a mechanical oscillator. One outstanding experimental challenge has been to explore the relationship between these phenomena. I will present data obtained using a superconducting cavity optomechanical system wherein a mechanical oscillator is driven by “nonclassical” radiation pressure forces imparted by squeezed microwave fields.
