我们提出了一种技术来诱导原子之间有效的、可控的相互作用，该技术基于拉曼散射进入以慢群速度传播的光学模式。由此产生的激发对应于自旋翻转原子对的创建，其方式类似于光学参量放大中的关联光子发射。这项技术可用于快速产生纠缠原子系综、自旋压缩以及在量子信息处理中的应用。
We suggest a technique to induce effective, controllable interactions between atoms that is based on Raman scattering into an optical mode propagating with a slow group velocity. The resulting excitation corresponds to the creation of spin-flipped atomic pairs in a way that is analogous to correlated photon emission in optical parametric amplification. The technique can be used for fast generation of entangled atomic ensembles, spin squeezing, and applications in quantum information processing.
