Title:
Monogamy of quantum correlations

Abstract:
Monogamy, a non-classical feature, that limits the sharability of quantum correlations among the subsystems of a multipartite quantum system has potential applications in quantum information theory. From previous studies on three-qubit states, we know that quantum correlations may satisfy or violate monogamy for quantum states. In my talk I will discuss which nonclassical correlation measures and classes of quantum states, under what conditions, satisfy monogamy. In particular, we find that higher number of parties enforce monogamy of quantum correlations for "almost all" states. We also obtain upper and lower bounds on monogamy scores.
