Abstract

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.

Probabilistic Dense Coding for Multi-communications with Non-maximally Entangled State

Ren Shijie, Xin Su

Probabilistic dense coding in the case of three energy-level non-maximally quantum entangled states between three parties has been investigated in this paper. By introducing an auxiliary particle and performing a collective unitary operation, dense coding of non-maximally entangled state is succeeded with certain probability. The coding scheme for multi-communications between N+1-parties is generalized by partly entangled state.

Probabilistic Dense Coding Using Non-Maximally Entangled Three-Particle State

Zhang Guo-hua, Yan Feng-Li

We present a scheme of probabilistic dense coding via a quantum channel of non-maximally entangled three-particle state. The quantum dense coding will be succeeded with a certain probability if the sender introduces an auxiliary particle and performs a collective unitary transformation. Furthermore, the average information transmitted in this scheme is calculated.
