| 摘 要： | 提出利用四个二粒子部分纠缠态作为量子信道,实现四粒子任意纠缠态的概率隐形传输的两种方案.发送者做四次Bell基测量,然后接收者通过引入辅助粒子并做适当的幺正变换,就能以一定的概率完成四粒子纠缠态的隐形传输.由变换算符出发,利用变换算符之间的关系给出两种方案的理论分析.

| Abstract: | Four partially entangled two-particle states are used as the quantum channel.Two schemes for probabilistic teleportation of an arbitrary four-particle entangled state are presented.The entangled state can be perfectly teleported probabilistically from the sender to the receiver if the sender performs four Bell-state measurements while the receiver introduces auxiliary particles and performing appropriate unitary transformations.Based on transformation operator,the theoretical explanation of two schemes is g... |
