摘要
The quantum discord was introduced by Ollivier, Zurek, Henderson, and Vedral as an indicator of the degree of quantumness of mixed states. In this paper, we provide a decomposition condition for quantum discord. Moreover, we show that under the condition, the quantum correlations between the quantum systems can be captured completely by the entanglement measure. Finally, we present examples of our conclusions.
