量子态的概率隐形传态

Probabilistic teleportation of quantum state

利用多方控制代理的网络,提出了一个量子隐形传态多量子位的协议。协议中所使用的量子信道有别于已有协议中所使用的量子最大纠缠态。得到的研究结果是,只有在发送方和多方代理合作时,接受方才能得到概率隐形传态的量子信息。因为使用的量子信道是非最大纠缠态,所以该协议更具有实际意义。

This paper describes a protocol for multi-qubit quantum teleportation between two parties by using the networks with control of many agents.This method is different from the proposed method recently.The result is that the senders can only probabilistic restore the qubit even if all the agents cooperate with the receiver.And the quantum channels are not maximally entangled state,so the protocol has the practical significance.
