摘      要：Quantum correlations in a family of bipartite separable qubit-qutrit quantum-classical correlated states are investigated by using two popular measures,i.e.,the original quantum discord(OQD)method by Ollivier and Zurek[***.88(2001)017901]and the measurement-induced disturbance(MID)method by Luo[***.A 77(2008)022301].It is found that both of them are functions of a parameter partially characterizing the concerned states,however,quantum correlations evaluated via the convenient MID method are somewhat overestimated.
