摘要
提出了当量子通道为非最大纠缠态时的概率密集编码方案 ,通过引入辅助粒子和进行联合么正变换 ,量子密集编码以一定概率实现 .
A scheme for probabilistic dense coding by partly pure entangled two-particle state is proposed. By introducing an auxiliary particle and performing a collective unitary operation, quantum dense coding will be succeeded with certain probability.
