Abstract

In this study, a method for entangling two spatially separated output laser fields from an optomechanical cavity is proposed. In the existing standard methods, entanglement is created by driving the two-mode squeezing part of the linearized optomechanical interaction;, however our method generates entanglement using the quantum back-action nullifying meter technique. As a result, entanglement can be generated outside the blue sideband frequency in both resolved and unresolved sideband regimes. We further show that the system is stable in the entire region where the Duan criterion for inseparability is fulfilled. The effect of thermal noise on the generated entanglement is examined. Finally, we compare this technique with standard methods for entanglement generation using optomechanics.

利用光力学实现传播光模式之间的连续可变纠缠
本研究提出了一种方法,用于纠缠光机械腔中两个空间分离的输出激光场。在现有的标准方法中,纠缠是通过驱动线性化光机电相互作用的双模挤压部分产生的;而我们的方法是利用量子反作用无效计技术产生纠缠。因此,纠缠可以在蓝色边带频率之外的解析和非解析边带状态下产生。我们进一步证明,该系统在满足不可分性段准则的整个区域内都是稳定的。我们还研究了热噪声对产生的纠缠的影响。最后,我们将该技术与使用光学机械生成纠缠的标准方法进行了比较。
