Resumen en inglés We study thermal superdense coding in a two-spin model under an external magnetic field. Its dependencies on magnetic field, strength of the spin squeezing and temperature are presented in detail. Our main goal now is to study how we can increase the thermal superdense coding capacity in the presence of magnetic field, strength of the spin squeezing and temperature. It shows that the dense coding tends to a valid value by setting the value of input quantum correlations. Our most important motivation for this study is to examine the relationship between the thermal properties of super quantum discord (SQD) and dense coding. The results show that the thermal properties of the SQD on our channel enable us to determine when and under what conditions the system is suitable for valid dense coding. Our proposals could be lead to that this scheme is efficient for quantum information processing
