摘　　要：基于七粒子纠缠态信道,提出一种三粒子一般态的远程控制传送方案.发送者进行投影测量后,发布测量结果.在控制者的控制下,接受者根据发送者的测量结果对所在处的粒子进行适当的幺正操作从而重构原始态.此方案可用来实现控制量子通信.A controlled teleportation scheme of a three-particle arbitrary state is proposed,in which a seven-particle entangled state is used as quantum channel. After projective measurement, the sender announces measurement results. Under the control of the controller,the receiver performs unitary operations on particles to reconstruct the original state. Using the controlled teleportation scheme, some controlled quantum communication protocols can be realized.
