摘要

我们证明了与外部高斯环境相互作用的二部高斯量子系统可能具有唯一的高斯纠缠定态，并且任何初始态都收敛于该定态。我们讨论了纠缠态对温度和相互作用强度的依赖性，并表明只有在低温和弱相互作用下才能找到纠缠态。

Environment-induced entanglement in Gaussian open quantum systems

We show that a bipartite Gaussian quantum system interacting with an external Gaussian environment may possess a unique Gaussian entangled stationary state and that any initial state converges toward this stationary state. We discuss dependence of entanglement on temperature and interaction strength and show that one can find entangled stationary states only for low temperatures and weak interactions.
