Optical entanglement facilitated by a hot mechanical oscillator

Aleksandr V. Karpenko, Andrey B. Matsko, Sergey P. Vyatchanin

Optomechanical generation of entangled optical beams is usually hindered by thermal noise. We present a theoretical study of low frequency entanglement generation between two optic…
