提出了一个通过三粒子纠缠GHZ状态传输未知的二粒子纠缠GHZ型状态的方案,对应于发送者测量结果的酉变换被详细给出,且成功的概率是1.为了推广该方案,提出了利用四粒子纠缠GHZ态作为量子信道的单受控隐形传态方案,并推广单受控到多受控的情况.在通过六粒子纠缠GHZ态单受控三方传态的基础上,提出了多受控多方传态方案.在这些控制方案中,任何一个接收者在其它接受者和受控者的帮助下都可重构原始态.但是任何一个控制者仅仅依靠其自己的粒子是不能恢复到原始态.我们获得了接受重构的酉运算与发送者、控制者和其它接受者的测量结果之间关系,且总体方案成功的概率是1.
The scheme for teleportation of an unknown two-particle entangled GHZ-type state via a three-parti- cle entangled GHZ state is presented, the unitary transformations corresponding to the measurement results of the sender are given in detail and the possibility of the total teleportation is one. In order to promote this scheme, the single controlled teleportation using four-particle entangled GHZ state as a quantum channel is put forward, and we generalize this single controlled scheme to multiple controlled case. Based on studying single controlled tripartite teleportation via a six-particle entangled GHZ state, the scheme of multiple controlled multiparty teleportation is proposed. In these controlled scheme, any one of the receivers can restore the original state with the help of the other receivers and controllers, but any one of the controllers cannot restore the original state by his/her own particle alone. We obtained the corresponding relationships among the unitary operations of reconstructing receiver, sender's measurement results, controllers' measurement results and the other receivers' measurement results, and the total probability of successful teleportation is one.
