摘要
提出了二粒子部分纠缠态的量子隐形传递控制方案.在该方案中,以四个二能级粒子GHZ态作为量子通道,把量子通道中的一个粒子作为控制粒子.在传递者和控制者进行一系列的量子操作和测量之后,根据他们的测量结果,接收者再进行适当的变换就能得到待传递粒子的量子态.
Abstract
A scheme is presented to realize the controlled teleportation of an unknown two-particle partly entangled state using a four-particle GHZ state as the quantum channel,and one of the particles in the channel is used as the controlling particle. After a series of quantum operations and quantum measurements performed by sender and controller,the receiver will get the quantum state which the sender seek to send by doing a series of quantum transformations which according to the sender and controller's measurement results.
