Abstract
We investigate the general monogamy and polygamy relations satisfied by quantum correlation measures. We show that there exist two real numbers and such that for any quantum correlation measure is monogamous if and polygamous if for a given multipartite state . For , we show that the monogamy relation can be superactivated by finite copies of for nonadditive correlation measures. As a detailed example, we use the negativity as the quantum correlation measure to illustrate such superactivation of monogamy properties. A tighter monogamy relation is presented at last.
