摘要
考虑初始处于EPR态的两个二能级原子A、B,将B原子注入处于真空态和单光子态的叠加态的腔中,演化一段时间后,对B原子进行选择性测量,通过选择合适的腔场初始叠加状态和演化时间,可控制原子A的偶极矩压缩效应.
Considering two two-level atoms （A and B） initially in the EPR state, we put atom B into one cavity that is prepared in a superposition of a zero and a single photon Fock state. When atom B flies out of the cavity, we make an arbitrary state measurement on it. The dipole squeezing of atom A can be controlled via choosing appropriate superposition state of the initial cavity field and evolution time.
