摘要 提出了当量子通道为三能级粒子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;计算了该方案的平均传输效率. A scheme for probabilistic dense coding by partly pure entangled three-level particle state is proposed.By introducing an auxiliary particle and performing a collective unitary operation,quantum dense coding will be succeeded with certain probability.The average capacity of this scheme is calculated.
