利用双模腔场与V型三能级原子共振作用隐形传送未知原子态
Teleportation of an Unknown Atomic-entangled State via the Interaction of V-type Three-level-atom with Two-mode Cavity Field
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.
Abstract
Time evolution of state vector of the system of 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 teleported state,it follows that the teleportation of an unknown atomic-entangled state is realized.And the scheme is experimentally feasible based on the current cavity QED technique and the success probability is 1/16.
