A useful scheme is suggested for generation of robust stationary entanglement between bipartite subsystems in two cavity optomechanics, which are either spatially separated or coupled through photon hopping process and are both driven by a squeezed coherent light. The transfer of correlations from entangled light source to optical cavity is investigated and the effects on the bipartite intracavity entanglement are presented. We conceptually calculate the degree of entanglement of the bipartite subsystems using the logarithmic negativity. We illustrate that the degree of stationary bipartite entanglement depends on the coupling strength between the cavities and is vigorous with respect to the evident environment temperature from one side and to the certain degree of the input thermal squeezed light. The problem of transferring quantum correlations from an entangled light source to initially separable or coupled cavity optomechanics is at the heart of concern with storage of quantum correlations in quantum memories for continuous variable quantum information processing and quantum-limited displacement measurements.

压缩光驱动的光机腔中的二分纠缠

提出了一种有用的方案，用于在两个腔光机械中的二分子系统之间产生稳健的固定纠缠，这些子系统在空间上分开或通过光子跳跃过程耦合，并且都由压缩的相干光驱动。研究了从纠缠光源到光学腔的相关性转移，并介绍了对二分腔内纠缠的影响。我们使用对数负性从概念上计算二分子系统的纠缠度。我们说明静态二分纠缠的程度取决于腔之间的耦合强度，并且相对于来自一侧的明显环境温度和输入热压缩光的一定程度是剧烈的。
