摘　　要：本文提出了一种基于两个三粒子部分纠缠GHZ态的任意两粒子远程态制备方案。此制备协议并不需要引入辅助粒子,总体成功概率等于纠缠通道两个最小幅值模平方之积。结合具体幺正矩阵与测量基形式,本文给出了制备协议实现步骤。当纠缠通道取为两个最大纠缠GHZ态时,总体成功概率则等于1/4。In this paper, we presented a novel scheme for probabilistic remote preparation of arbitrary two-qubit state via two three-qubit GHZ states. Any auxiliary particles need not to be introduced in our proposal. The total successful probability is equal to the square of the norm of the minimum amplitude coefficients of the partially entangled channel. The concrete processe of this scheme is presented via some appropriate local unitary operations and measurement basis. When quantum channel is composed of two three-qubit maximally entangled states, the successful probability is equal to 1/4.
