利用二粒子纠缠态隐形传递未知二粒子量子态

摘要

This paper uses a special two-particle entangled state as a quantum channel to achieve invisibility unknown arbitrary two-particle quantum state teleportation. It makes contrast with Yuan, who makes use ofχ-type entangled states to achieve two any unknown quantum state teleportation scheme. The scheme uses two sub-channels and Bell-based measure-ments, as well as special unitary operation successfully completing message teleportation. The program uses fewer resources, and the obtained probability of an original information is 1.%提出了一个利用特殊的二粒子纠缠态作为量子信道来实现任意二粒子未知量子态的隐形传态。对比Yuan等人提出的利用χ纠缠态实现的任意未知二量子态的隐形传态方案。该方案利用二粒子信道和Bell基测量，以及特殊的幺正操作顺利完成信息的隐形传态。而且方案中利用了较少的资源，且获得的原始信息的概率为1。
