我们提出了一种腔耗散方案来制备处于压缩纠缠态的原子系综和运动镜的混合系统。该方案是基于原子中的四波混频和镜上的辐射压力，这两者联合收割机导致原子和镜与腔场的Bogoliubov相互作用。在绝热条件下，腔场使混合Bogoliubov模演化到真空态，对应于双模压缩纠缠态。混合纠缠对系统参数的依赖性也在Bogoliubov相互作用中和之外得到了体现。
We present a cavity dissipation scheme to prepare a hybrid system of an atomic ensemble and a moving mirror in squeezed and entangled states. This scheme is based on four-wave mixing in the atoms and radiation pressure on the mirror, both of which combine to lead to Bogoliubov interactions of the atoms and the mirror with the cavity fields. Under adiabatic conditions, the cavity fields cause the hybrid Bogoliubov modes to evolve into the vacuum states, which correspond to the two-mode squeezed and entangled states. The dependence of the hybrid entanglement on the system parameters is also presented in and beyond the Bogoliubov interactions.
