摘要

量子纠缠和Einstein-Podolsky-Rosen (EPR)导向是量子信息处理中的宝贵资源。研究了在弱压缩真空场作用下，如何增强光机耦合系统的量子纠缠和EPR转向。与真空环境相互作用相比，施加压缩真空场时，系统的量子纠缠和EPR转向更强。大程度的压缩真空场不利于增强量子纠缠和EPR导向。在该模型中起关键作用的不是压缩真空场的压缩参数，而是参考相。

Enhancing the quantum entanglement and EPR steering of a coupled optomechanical system with a squeezed vacuum field

Quantum entanglement and Einstein-Podolsky-Rosen (EPR) steering are valuable resources in quantum information processing. How to enhance the quantum entanglement and EPR steering of coupled optomechanical systems with a weak squeezed vacuum field are studied when the displacement of detuning induced by the mechanical mode is considered. Compared with the condition that the system interacts with a vacuum environment, the quantum entanglement and EPR steering are stronger when the squeezed vacuum field is applied. A squeezed vacuum field with a large degree is not beneficial to enhance the quantum entanglement and EPR steering. Rather than the squeezing parameter of the squeezed vacuum field, the reference phase plays a vital role in this model.
