Studying non-classical states of macroscopic systems will enable to test quantum mechanics in unexplored regimes, leading to new fundamental insights as well as practical outcomes for quantum information processing and communication.
I will show how to use the radiation pressure interaction in recently developed optomechanical cavities to prepare a macroscopic oscillator in a non-classical state of motion, namely a single-phonon Fock state. The scheme relies on projective measurement of the oscillator vibration upon the detection of a single scattered photon, and is realizable within the parameter regime of state-of-art experiments. The single phonon is generated in a heralded way and can be released, on-demand, as a single photon — with potential applications in quantum repeaters for long-distance quantum key distribution.
I will conclude with an overview of our experimental efforts based on photonic crystal nanobeam cavities toward the demonstration of the scheme.
