Probabilistic Dense Coding Using Non-Maximally Entangled Three-Particle States
Zhang Guo-hua, Yan Feng-Li
Abstract
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.
