摘要
提出一种多人控制的三粒子GHZ纠缠态的量子隐形传送方案,为了实现传送,Alice需要对自己的三对粒子实施Bell测量并将结果通知Bob,异地的众多监控者对各自的控制位粒子实施Hadamard变换和投影测量。接受者Bob在Alice和所有监控的者发送的经典信息的协助下只需要施行简单的幺正变换就能成功实现量子态的隐形传送,传送过程中任意一个参与者的缺席都将导致传送的失败。
A scheme for teleporting an unknown three-qubit GHZ state under the control of many supervisors is presented. In order to realize the teleportation, the sender Alice needs to perform Bell state measurements on her qubit pairs and all the spatially-separated supervisors should make a Hadamard transformation and a Von Neumann measurement on their own qubit, respectively. Then the receiver Bob can restore the original state by operating some pauli matrixes with the aid of classical message from Alice and supervisors. Anyone＇ s absence will surely fail the teleportotion.
