记忆效应诱导的宏观-微观纠缠

Memory effect induced macroscopic-microscopic entanglement

Qingxia Mu, Xinyu Zhao, Ting Yu

摘要:

研究了非马尔可夫环境中光场与可动镜耦合的光机纠缠。利用非马尔可夫量子态扩散(NMQSD)方法和非马尔可夫主方程研究了腔场与可动镜之间纠缠的产生。本文提出的简单模型展示了与环境记忆效应相关的光机械纠缠的几个有趣的性质。可见,有效环境中心频率可以用来调制光-机纠缠。此外,我们还证明了通过适当地选择有效失谐量可以获得最大的纠缠,而有效失谐量的大小与环境记忆效应的强度密切相关。

英文摘要:

We study optomechanical entanglement between an optical cavity field and a movable mirror coupled to a non-Markovian environment. The non-Markovian quantum state diffusion (NMQSD) approach and the non-Markovian master equation are shown to be useful in investigating the entanglement generation between the cavity field and the movable mirror. The simple model presented in this paper demonstrates several interesting properties of optomechanical entanglement that are associated with environment memory effects. It is evident that the effective environment central frequency can be used to modulate the optomechanical entanglement. In addition, we show that the maximum entanglement may be achieved by properly choosing the effective detuning which is significantly dependent on the strength of the memory effect of the environment.
