Characterization of tripartite quantum states with vanishing monogamy score
Characterization of tripartite quantum states with vanishing monogamy score
Quantum discord, an information-theoretic quantum correlation measure, can satisfy as well as violate monogamy, for three-party quantum states. We quantify the feature using the concept of discord monogamy score. We find a necessary condition of a vanishing discord monogamy score for arbitrary three-party states. A necessary and sufficient condition is …
