摘要
为实现未知的三粒子W纠缠态的隐形传递,提出利用非最大纠缠Cluster态和EPR对概率传送三粒子W纠缠态的隐形传态方案。发送者进行三次Bell基测量,接收者根据测量结果实施相应的幺正变换,通过构造幺正转换矩阵,可使因非最大纠缠信道导致的畸变的量子态得到恢复,最终可概率性实现纠缠W态的隐形传送。该方案给出了完成隐形传态的一种新思路,与已有方案相比,具有操作简便、易实现、节省量子信道纠缠资源的特点。
A scheme of teleportation of a three-particle W state via nonmaximally entangled Cluster state and EPR pairs is proposed. The sender performs three times Bell measure- ment, and the receiver carries out corresponding unitary transformation. By constructing uni- tary transformation matrix to recover the distorted quantum state by nonmaximally entan- gled quantum channel,we can realize the teleportation of W state. The proposed scheme provides a new idea to teleportation. Compared with the existing scheme, it is simple, easy for operation and easy to realize and it saves the resource of quantum channel.
