Abstract

Optical readout of mechanical devices, operated in both the classical and fully quantum regime, has opened unprecedented levels of sensitivity to small forces and displacements. This has been central to the successful measurement of gravitational waves with LIGO. Here I'll discuss applications of such opto-mechanical systems, ranging in size from single electrons to kilogram-scale masses, to searches for dark matter and for quantum signatures of the gravitational interaction. These detection problems necessitate the use of sensors operated at or beyond noise levels set by the Heisenberg uncertainty principle.
