中文摘要：

给出了量子通道为三能级三粒子非最大纠缠态的概率密集编码方案．通过引入辅助粒子，进行联合幺正变换，三能级三粒子非最大纠缠态的量子密集编码以一定概率实现．将三能级三粒子的编码方案推广到三能级多粒子态，实现了三能级粒子的多方通信；计算各方案的平均传输效率并与二能级粒子的进行比较．

英文摘要：

The scheme for dense coding by maximally and partly entangled three-level state between three particles are given in detail. By introducing an auxiliary particle and performing a collective unitary operation,dense coding of partly entangled state will be succeeded with certain probability. The scheme for probabilistic dense coding between multiparticles by an N ＋1-particle partly entangled state is generalized. The average capacity of those schemes are calculated and compared with the two-level＇s.
