The pairwise quantum correlations of symmetric multi-qubit states are studied by using the geometric measure of quantum discord (GMQD). The explicit expressions of the GMQD for the Dicke states and their superpositions are given. By comparing the GMQD with quantum discord, we conclude that they display similar behaviour. From the results, we know that most of the states we have considered exhibit pairwise quantum correlations.
