摘　　要：提出了制备三原子W态和一个处于最大纠缠的两原子态的方案 ,这些均基于三个原子同时与单模腔场相互作用实现的 与郑郭方案不同 ,本方案的腔场初始处于n光子的热态 ,因而具有更大的现实意义Following a recent scheme by Zheng and Guo, we propose protocols for the generation of three-atom W class of maximally entangled state and an interesting quantum state, which is also the maximally two-atom entangled state. These are based on the simultaneous interaction of three atoms with a single-mode cavity field. Unlike previous scheme, the cavity field in our scheme is initially in thermal states with n photons. Finally, suggestion for experimental probability is given.
