摘　　要：提出一个利用部分纠缠EPR对和W态作为量子信道,在可信第三方(Charlie)的控制下,发送方(Alice)进行3次Bell基测量、一次Hadmard变换和单粒子测量,接收方(Bob)引进一个辅助粒子,进行相应的幺正操作,则可以以一定的概率实现类团簇态的隐形传输.A scheme of teleportation of the cluster state was presented when a non-maximally entangled W state and two EPR pairs were used as quantum channels. With the help of Charlie, the teleportation could be successfully realized with a certain probability by performing three Bell measurements and a Hadmard operation on the sender＇ s side, and by introducing an auxiliary particle and performing unitary transformations on the receiver＇s side.

关 键 词：隐形传输 幺正变换 类团簇态
