Abstract

Vanishing quantum discord and the entropy correlations between subsystems in a bipartite system are investigated. We numerically verify that there exists a condition of complete entropy exchange between the two subsystems, and it is found that the condition is in excellent agreement with that of the nullity of quantum discord in a certain range of parameters of the bipartite system.
