There are two important paradigms for defining quantum correlations inquantum information theory, viz. the information-theoretic and theentanglement-separability ones. We find an analytical relation between twomeasures of quantum correlations, one in each paradigm, and show that only acertain cone-like region on the two-dimensional space spanned by these measuresis accessible to pure three-qubit states. The information-theoretic multipartyquantum correlation measure is related to the monogamy considerations of abipartite information-theoretic quantum correlation measure, while theentanglement-separability multiparty measure is the generalized geometricmeasure, a genuine multiparty entanglement measure. We also find an analyticalrelation between two multiparty entanglement measures, and again obtain acone-like accessible region in this case. One of the multisite measures in thiscase is related to the monogamy of a bipartite entanglement measure, while theother is again the generalized geometric measure. Just like in relativity,events cannot occur outside the space-time light cone, we analogously find herethat state points corresponding to pure three-qubit states cannot fall outsidethe two-dimensional cone-like structure between quantum monogamy scores and agenuine multisite entanglement measure.
