| 摘 要： | 席拥军等提出了一个利用三对任意纠缠的粒子作为量子通道对一个任意的三粒子态实现隐形传送的方案.在此方案中,接受者需要引入一个辅助二态粒子.由波函数的叠加原理与变换算符出发,提出一种方法,不需要引入一个辅助二态粒子,将体系的总量子态按Bell基展开,接受者直接对自己拥有的粒子进行相应的变换,可使这三粒子恢复原始量子态,从而实现概率为1的量子态的隐形传送.

| Abstract: | Xi Yongjun et al proposed a scheme of probabilistic teleportation of an arbitrary three particle entangled state via three pair nonmaximally entangled particles. In this scheme, receiver need use auxiliary particles to realize the teleportation. Not using two auxiliary particles, the system state is linear combination of Bell bases and transformation operator. If transformation operators have inverse operators, the teleportation can be realized by performing a inverse transformation. The relation of the determinant of transformation operators with entanglement measure is obtained. |
