摘　　要：给出了双模腔场与V型三能级原子共振相互作用下系统态矢的演化公式.利用V型三能级原子与双模腔场的相互作用,通过控制原子与光场的相互作用时间,并对待传送的原子态进行选择性探测,从而实现未知双原子纠缠态的隐形传送.该方案不需要进行Bell基测量,其成功几率为1/16.Time evolution of state vector of the system o{ V-type three-level-atom interacting with two-mode cavity field is obtained. An alternative scheme is proposed for teleportation of an unknown atomic entangled state without the Bell-state measurement. The scheme is based on the resonant interaction of V type three- level-atom with two-mode cavity field. By means of selective measurement on the atom to be state,it follows that the teleportation of an unknown atomic entangled state is realized. And the experimentally feasible based on the current cavity QED technique and the success probability is teleported scheme is 1/16.
