Optomechanical circuits for nanomechanical continuous variable quantum state processing — •Michael P.

Optomechanical crystals are novel on-chip realizations of an optomechanical system. Recently, Painter et. al. prepared the vibrational mode of such a structure in its quantum ground state by means of optical sideband cooling, opening the door to the investigation of its quantum dynamics. We propose and analyze an architecture, in which linear quantum operations can be performed selectively on the vibrational modes: By suitable modulation of the driving laser intensity, it is possible to generate entanglement, squeezing and state transfer between modes.
