Selective entanglement in a two-mode optomechanical system

TL;DR

This paper demonstrates that a two-mode optomechanical system can generate robust, selective bipartite entanglement between the mechanical and optical modes, enabling potential quantum information applications.

Contribution

It introduces a method to achieve and control selective bipartite entanglement in a three-mode optomechanical system under realistic conditions.

Findings

Three types of bipartite entanglement are achievable.

Entanglement persists at accessible temperatures.

Selective entanglement can be tuned via system parameters.

Abstract

We analyze an optomechanical system formed by a mechanical mode and the two optical modes of an optomechanical cavity for the realization of a strongly quantum correlated three-mode system. We show that the steady state of the system shows three possible bipartite continuous variable entanglements in an experimentally accessible parameter regime, which are robust against temperature. We further show that selective entanglement between the mechanical mode and any of the two optical modes is also possible by the proper choice of the system parameters. Such a two-mode optomechanical system can be used for the realization of continuous variable quantum information interfaces and networks.
