| 摘 要： | 提出一种类型三量子比特GHZ态远程制备(RSP)实现方案,利用两量子比特的最大纠缠态(即Bell态)作为量子信道,制备成功几率和经典信息消耗都被一一计算出来.就一般情况来说,根据Alice的测量结果,Bob以1/4的几率能够成功实现GHZ态的远程制备.但是,对于三类特殊态,经额外消耗经典信息后其成功几率能够大大提高至1.0.即此方案是决定性的.

| Abstract: | A remote state preparation(RSP) scheme of a three-qubit Greenberger Horne Zeilinger(GHZ) class state was proposed by using three two-qubit maximally entangled states as the quantum channel.The success probability of preparation and classical communication cost were calculated.Generally speaking,according to Alice's classical message,with probability 1/4 Bob could successfully prepare the GHZ state.However,for three kinds of special states,the success probability of preparation could be increased to 1.0 afte... |
