摘　　要：主要研究了运用五粒子簇态作为量子通道来实现特殊形式的四粒子态的量子隐形传态方案.该方案运用了量子力学中量子纠缠的理论.在这个方案中,发送者只需要进行五粒子冯·诺依曼投影测量,接收者根据发送者的测量结果,通过在其量子位上执行一些适当的幺正变换得出原始的四量子比特状态.提出的这个方案可以很好地应对一般的窃听方式.This scheme mainly studies the quantum teleportation of a special form of four-particle state by using the five-particle cluster state as the quantum channel.This scheme mainly uses the theory of quantum entanglement in quantum mechanics.In this scheme,the sender only needs five-qubit Von-Neumann projective measurements,the receiver derives the original four-qubit state by performing some appropriate unitary operations on its qubit according to the result of the measurement of sender.The proposed program can be a good way to deal with the general eavesdropping.
