摘要
采用三粒子最大纠缠态作辅助量子信道,定义出能被Alice作联合测量的四个特殊的“GHZ”态,Bob实施简单操作,两粒子纠缠态(EPR对)的量子隐形传递顺利达成。
Abstract
A scheme of a two-particle entangled state via entanglement swapping is proposed.By using a three-particle entangled state as a quantam channel,a “GHZ” state is defined,wich can beused by Alice for joint measwrement.When Bob performs a corresponding unitary tramsformation,quantum teleportation of a two-particle entangled state can be successfully realized.
