摘要： 提出了一种利用V型三能级原子与大振幅相干态腔场的Raman 相互作用来制备相干压缩纠缠态的方案.在这个方案中，一个V型三能级原子连续通过多个处于压缩相干态的腔，通过 Raman 相互作用，整个系统处于纠缠态.而后，对原子进行探测，则腔场组成的系统坍缩到多模压缩相干纠缠态.

Abstract: A scheme was presented for the generation of bipartite and multipartite entangled squeezed coherent states. In the scheme, a V-type three-level atom was sent through many single-mode cavities filled with squeezed coherent field. The whole system was entangled via the atom-cavity Raman interaction. Then detection the atom leaves the cavity system in an entangled state.

Key words: Raman interaction, V-type three level atom, squeezed coherent state, quantum entanglement, Raman interaction, V-type three level atom, squeezed coherent state
