Multi-party dense coding in non-symmetric quantum channel

Abstract

A three- and an ( N +1)-party dense coding scheme in the case of non-symmetric Hilbert spaces of the particles of a quantum channel are investigated by using a multipartite entangled state. In the case of the ( N +1)-party dense coding scheme, we show that the amount of classical information transmitted from N senders to one receiver is improved.

Dense Coding Plan of Using a Non-symmetric Multipartite Quantum Channel

Fan Qiu

A dense coding scheme which employs non-symmetric two-particle entangled state as quantum channel is advanced.By way of theoretical deduction,the two-particle state is extended to multipartite state: namely,the sender(Alice) and the receiver(Bob) carry along coding by making use of the shared N particle beams in non-symmetric Hilbert space.As a result,the efficiency of information transmission is dramatically increased.

A Scheme for Dense Coding in the Non-Symmetric Quantum Channel

Yan Feng-Li, Meiyu Wang

We investigate the dense coding in the case of non-symmetric Hilbert spaces of the sender and receiver's particles sharing the quantum maximally entangled state. The efficiency of gaining classical information is also considered. We conclude that when a more level particle is with the sender, she can obtain a non-symmetric quantum channel from a symmetric one by entanglement transfer. Thus the efficiency of information transmission is improved.

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

Zhang Guo-hua, Yan Feng-Li

We present a scheme for probabilistic dense coding via quantum channels of non-maximally entangled three-particle states. Quantum dense coding will succeed with a certain probability if the sender introduces an auxiliary particle and performs a collective unitary transformation. The average information transmitted in this scheme is calculated.

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.
