一般WGHZ态的量子概率隐形传输

摘要

提出了利用部分纠缠EPR对和四粒子类团簇态为量子信道,概率隐形传输一般WGHZ态的方案.发送方进行三次Bell基测量,接收方引入一个辅助粒子,进行一系列幺正变换,则以一定的概率成功地实现隐形传态.%A scheme of teleportation of the general WGHZ state was presented when a non-maximally entangled cluster state and an EPR pair were used as quantum channels. It was shown that teleportation could be successfully realized with a certain probability by performing three Bell-state measurements on the sender' s side and by introducing an auxiliary particle and performing a unitary transformation according to the measurement result, conditioning on the possible receiver' s side.
