Progress in the technology of optomechanical systems is reaching the point where the mechanical action of a single photon can be significant. In this talk I will describe how single photon states can be used to control the quantum state of a mechanical resonator coupled via radiation pressure to the light in a cavity. The photons can be used as a quantum probe of the mechanical state . This enables the engineering of non classical states of the mechanical oscillator with applications to metrology and experiments to look for gravitational decoherence.
