论文摘要
我们研究了光学机械系统中重力诱导的纠缠现象。假设光子数量保护和牛顿电位扩展到振荡器位置的二次顺序，我们正好解决了Optomehcanical Systems的动力学。然后，我们发现牛顿重力引起的相位差会导致分离腔中光子的纠缠较大。我们以精确的方式阐明了光学机械系统中大重力引起的纠缠的生成机制。我们还确定了产生最大光子纠缠的特征时间。最后，通过将特征时间与由于光子泄漏引起的变质时间进行比较，我们评估了测试重力诱导的纠缠所需的耗散率的范围。
We investigate the phenomenon of gravity-induced entanglement in optomechanical systems. Assuming photon number conservation and the Newtonian potential expanded up to the quadratic order of the oscillator positions, we exactly solve the dynamics of the optomehcanical systems. Then, we find that the phase difference due to the Newtonian gravity leads to the large entanglement of photons in separated cavities. We clarify the generating mechanism of large gravity-induced entanglements in optomechanical systems in an exact manner. We also determine the characteristic time to generate the maximal entanglement of photons. Finally, by comparing the characteristic time with the decoherence time due to photon leakage, we evaluate the range of the dissipation rate required for testing the gravity-induced entanglement.
