论文摘要
我们展示了如何通过将Tweezer光子连贯散射到单个腔模式下产生和检测两个光学悬浮的纳米颗粒之间的纠缠。通过检测Stokes Photon的触发，镊子引发的呼声从蓝色切换到红色。然后，通过机械节拍频率振荡的条件抗螺旋光子通量来验证纠缠。拟议的设置可通过近乎未来的技术实现，并为两个或更多悬浮的纳米级对象之间的非经典质量中心相关性首次实验性观察打开了大门。
We show how entanglement between two optically levitated nanoparticles can be generated and detected by coherent scattering of tweezer photons into a single cavity mode. Triggered by the detection of a Stokes photon, the tweezer detuning is switched from the blue to the red; entanglement is then verified by the conditioned anti-Stokes photon flux, which oscillates with the mechanical beat frequency. The proposed setup is realizable with near-future technology and opens the door to the first experimental observation of non-classical center-of-mass correlations between two or more levitated nanoscale objects.
