| 摘 要： | 本文提出了多个控制者参与的量子态受控传递方案。在该方案中,除了传递者Alice对其拥有的两个粒子作Bell基联合测量外,两个控制者大Charlie和小Charlie还必须对其拥有的控制粒子进行量子操作和测量,才能将未知量子态由Alice处传递到Bob处。此外,还研究了引入辅助粒子的方法来实现该受控传递的方案。

| Abstract: | A scheme is presented to realize the teleportation of an unknown quantum state under the control of multi - users. On condition that Alice, the sender, performs a Bells joint measurement on the two particles in her hands. And big Charlie as well as small Charlie, the two controllers, respectively perform a quantum transformation and quantum measurement on the particles in their hands in this scheme. The unknown quantum state will be successfully teleported. Furthermore, a method of introducing an auxiliary particle is used to realize the controlled teleportation. |
