The role of super quantum discord in super dense coding

Quantum correlations have been comprehensively accepted as the main resource for different quantum information processing tasks.  If we regard density coding as a process for transmitting information from source to receiver, it is important to understand how the properties of the quantum channel itself can be determined, and under what conditions the channel is suitable for density coding.  This study considers super dense coding of a bipartite state via a quantum correlated channel. We find that the dynamic properties of SQD on our channel enable us to determine when and under what conditions the system is suitable for dense coding capacity. The results show that our proposals could lead to this scheme being efficient for quantum information processing.
