| 摘 要： | 提出了一个较好的远程制备多粒子的纠缠态的方案,先讨论用(N+1)粒子的纠缠态作为量子通信信道制备2N粒子的纠缠态.然后在研究用一个(N+1)粒子的纠缠态和一个(N+2)粒子的纠缠态作为量子通信信道制备(2N+1)粒子的纠缠态.与现在已有人提出的制备多粒子的纠缠态的方案相比,这个方案的优点是仅花费了两位经典位和只有一次两粒子的投影测量.

| Abstract: | In this paper a optimize scheme for remote preparation of multiparticle entangled state is proposed.In the first phase of our discuss,it is remote preparing a 2N particle entangled state via two(N+1)particle GHZ states as the quantum channels,and then,in the next step remote preparing a(2N+1) particle entangled state by using a(N+1) particle GHZ state and a(N+2) particle GHZ state as the quantum channels is studied.Comparing with the schemes which has been raised before,an obvious advantage is strongly presented that only two classical bits and one two-particle projective measurements are applied in this scheme. |
