| 摘 要： | 研究了利用n个Einstein-Podolsky-Rosen(EPR)对作为量子通道实现n粒子任意态的量子隐形传送.在方案中,我们找到了通常量子隐形传态过程中发送者Alice的Bell基测量结果与接收者Bob的幺正操作之间的内在联系,得出了它们之间的一一对应关系,从而使得Bob收到Alice的Bell测量信息后可确定他要对粒子执行的幺正操作以完成隐形传态任务.这对于当n趋于很大时是尤其重要的.

| Abstract: | A scheme for teleportation of n-particle arbitrary states via n pairs of EPR states is proposed.In the scheme,we discovered the internal relationship between the result of Alice's measurement and the unitary transformation performed by Bob(the receiver),and the corresponding expressions were described.Thus when Bob receiving the result of Alice' Bell measurement,he can ascertain immediately the corresponding unitary transformation he must performed in order to implement the teleportation protocol,which is particularly important for the case that n is very large. |
