摘　　要：　往光腔中注入２ 个Ｖ型三能级原子使其与腔场发生Ｒａｍａｎ 相互作用，接着再往光腔中注入第３ 个原子， 此原子是处于共振态的二能级原子， 最后对原子３ 和光场进行测量， 便可得到原子１ 和２ 的纠缠态．Two V type three level atom 1 and atom 2 simultaneously through the cavity with the frequency being chosen appropriately so that the atoms undergo a Raman transition during their interaction with the cavity. Secondly, a resonant two level atom 3 is injected into the cavity field. Finally, we can get the entangled state of atom 1 and atom 2 via measuring the states of atom 3 and the cavity.
