| Abstract: | 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. |
