摘要

提出通过一个四粒子cluster非最大纠缠态作为量子信道来实现一未知两粒子纠缠态的量子几率隐形传态方案。在此方案中

纠缠态可以实现一定的几率传输

此几率由cluster态中绝对值较小的两个系数决定。如果我们用cluster最大纠缠态作为量子信道

此时几率隐形传态就成了一般的隐形传态

即成功传输的几率为100%。

Abstract

A scheme for probabilistic teleportation of an unknown two-particle entangled state via a four-qubit non-maximally entangled cluster state as quantum channel is proposed. In this scheme

the unknown entangled states can be teleported with a certain probability

which is determined by the smallest two of the coefficients absolute values of the cluster state. What's more

if quantum channel is maximally entangled cluster state

the probabilistic teleportation becomes usual teleportation.
