Based On The Non-symmetric Many-body Quantum Dense Coding Channel

We investigate dense coding by using non-symmetric multipartite quantum channel. Where "non-symmetric" indicates the particles which are shared by sender and receiver are in the non-symmetric Hilbert space. In this article, we firstly propose a dense coding scheme by using maximally non-symmetric multipartite quantum channel, and compare the information of non-symmetric channel to the symmetric one's; and then, we also propose another scheme for probabilistic dense coding by using non-maximally non-symmetric multipartite quantum channel, and discuss the relationship between average information and the coefficients of the non-maximally entangled states which compose the quantum channel.
