未知单粒子态及其正交态的概率复制

Probabilistic Cloning and Orthogonal Complementing of an Unknown State

提出了未知单粒子态及其正交态的概率复制方案:Victor是未知单粒子态的制备方,Alice和Charlie是发送方,Bob是未知态的接收方,且Alice,Bob,Charlie对未知态的信息一无所知.首先,Alice,Charlie,Bob之间进行量子隐形传态过程,使Bob获得未知态;接着,在Victor的帮助下,即Bob对单粒子进行测量,在Alice,Charlie处实现未知态或者其正交态的概率复制.

A scheme for probabilistic cloning of an unknown state and its orthogonal complete state witn assistance offered by state preparer （Victor） is proposed. The first stage of this scheme is to teleport an unknown state to the receiver （Bob）. The second stage of this scheme is that the senders （Alice and Charlie） get the same unknown state or an orthogonal complement copy of an unknown state with the help of Victor.
