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。A scheme of a two-particle entangled state via entanglement swapping is proposed. By using a three-particle entangled state as a quantum channel, a ＂GHZ＂ state is defined, which can be used by Alice for joint measurement. When Bob performs a corresponding unitary transformation, quantum teleportation of a two-particle entangled state can be successfully realized.

关 键 词：量子隐形传态 GHZ态 量子信道 联合测量 最大纠缠 幺正变换
