摘　　要：提出了一种用真实的四体最大纠缠态实现两体任意量子态的隐形传送方案,构建了16个正交完备基矢,这些基矢都是真实的四体纠缠态,即不能写成直积的形式.该方案揭示了一种四体纠缠态的某种特殊纠缠属性,并表明从某种意义上来讲,还可以从这样的一个四体纠缠态中提取出2个Bell态的纠缠.A scheme for teleportation of two-partite arbitrary states via genuine four-partite entangled states is proposed. In the scheme, 16 orthogonal and complete bases are constructed. All the bases are genuine four-partite entangled states, none of which is reducible. The scheme reveals some particular properties of the related four-partite entangled state, and indicates that in some sense the amount of entanglement of two Bell states can be abstracted from any one of the four-partite states.

关 键 词：四体最大纠缠态 两体任意量子态 正交完备基矢 量子隐形传态
