论文摘要
我们提出了一个方案，如何通过短的光学脉冲和测量方法在两个机械模式与单个光腔耦合到单个光腔之间的两部分高斯纠缠。我们的协议既不需要解决的边带状态，也不需要低热声子占用率，并且允许在不到机械运动时期内生成和验证量子纠缠。纠缠是通过有效的两种模式机械挤压通过调节位置测量而产生的。我们研究了机械频率和光力耦合率的实验偏差纠缠的鲁棒性。
We propose a protocol how to generate and verify bipartite Gaussian entanglement between two mechanical modes coupled to a single optical cavity, by means of short optical pulses and measurement. Our protocol requires neither the resolved sideband regime, nor low thermal phonon occupancy, and allows the generation and verification of quantum entanglement in less than a mechanical period of motion. Entanglement is generated via effective two-mode mechanical squeezing through conditioning position measurements. We study the robustness of entanglement to experimental deviations in mechanical frequencies and optomechanical coupling rates.
