摘要
该文以4个二粒子最大纠缠态作为量子信道,研究了Alice将一个未知的四粒子团簇态(clusterstate)传送到远距离的接收者Bob的隐形传态过程.由于四粒子团簇态的特殊性质,接收者Bob只须施行64种可能的局部酉变换便能接收到Alice传送的未知态,从而实现了四粒子团簇态的量子隐形传态.
We investigate a process of quantum teleportation that Alice teleports an unknown four-particle entangled cluster state to a distance receiver Bob through four two-particle the most entangled state quantum channels.As the property of four-particle cluster state,the receiver Bob can receive the unknown state coming from Alice only to implement 64 kinds of local unitary transformations,there-by quantum teleportation of four-particle cluster state can be realized.
