Reservoir-engineered entanglement in optomechanical systems

摘要

We show how strong steady-state entanglement can be achieved in a three-modeoptomechanical system (or other parametrically-coupled bosonic system) by usingone of the modes as a cold reservoir to effectively laser-cool a delocalizedBogoliubov mode. This approach allows one to surpass the bound on the maximumstationary intracavity entanglement possible with a coherent two-mode squeezinginteraction. Unlike typical dissipative entanglement schemes, the entanglingdynamics here are most effective in a regime where the effects of theengineered reservoir cannot be described by a Markovian Lindblad masterequation.
