Probabilistic Dense Coding Using Non-Maximally Entangled Three-Particle State
arXiv:0902.3711
Abstract
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.
