利用cluster态隐形传送任意三原子W态
Teleportation of an arbitrary three-atom W state with cluster state
摘要
Abstract
A scheme for teleportation of an unknown three-atom entangled W state is proposed,in which a cluster state of four identical two-level atoms is used as quantum channel.It is proved that,an arbitrary three-atom entangled W state can be teleported perfectly by introducing an additional atom and performing a collective unitary transformation as well as appropriate single-atom unitary transformations on the receivers side based on the classical information of the sender.In the scheme,the effects of the thermal field and the cavity decay are eliminated.Furthermore,the Bell measurements are not needed,and the successful probability of teleportation is 1.关键词
