Abstract

We study thermal dense coding in a two-spin model under an external magnetic eld. Its depen-
dencies on magnetic eld, strength of the spin squeezing and temperature are presented in detail.
Our main goal now is to study how we can increase the thermal dense coding capacity in the presence
of magnetic eld, strength of the spin squeezing and temperature. It shows that the dense coding
tend to valid value by setting the value of the input quantum correlations. Our most important
motive for this study is to examine the relationship between the thermal properties of super quan-
tum 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.
