摘要
以十粒子团簇态为量子信道,提出一个关于任意二粒子纠缠已知态的对称受控双向远程制备协议.该方案表明,在监察者Charlie的控制下,Alice和Bob能够为彼此同时、远程地制备任意二粒子纠缠态.在量子信息的传输过程中,Alice和Bob借助各自掌握的信息和采用前馈策略来构造恰当的策略基,通过经典通信和局域操作,就能以100%的概率成功实现任意二粒子态的远程制备.
A protocol of symmetric controlled bidirectional remote preparation for arbitrary two-particle entangled known states is proposed using ten-particle cluster states as quantum channel. This scheme shows that under the control of Charlie, Alice and Bob can simultaneously and remotely prepare any two-particle entangled states for each other. In the process of quantum information transmission, Alice and Bob use their own information and feed-forward strategy to construct the appropriate strategy bases. Through classical communication and local operation, the remote preparation of arbitrary two-particle states can be successfully achieved with a 100% probability.
