    "abstract": "Based on the quantitative complementarity relations, we analyze thoroughly\nthe properties of multipartite quantum correlations and entanglement in\nfour-qubit pure states. We find that, unlike the three-qubit case, the single\nresidual correlation, the genuine three- and four-qubit correlations are not\nsuited to quantify entanglement. More interestingly, from our qualitative and\nnumerical analysis, it is conjectured that the sum of all the residual\ncorrelations may constitute a good measure for the total multipartite\nentanglement in the system.",
