    "abstract": "It is a central trait of quantum information theory that there exist\nlimitations to the free sharing of quantum correlations among multiple parties.\nSuch \u0027monogamy constraints\u0027 have been introduced in a landmark paper by\nCoffman, Kundu and Wootters, who derived a quantitative inequality expressing a\ntrade-off between the couplewise and the genuine tripartite entanglement for\nstates of three qubits. Since then, a lot of efforts have been devoted to the\ninvestigation of distributed entanglement in multipartite quantum systems. In\nthese proceedings we report, in a unifying framework, a bird\u0027s eye view of the\nmost relevant results that have been established so far on entanglement sharing\nin quantum systems. We will take off from the domain of N qubits, graze qudits,\nand finally land in the almost unexplored territory of multimode Gaussian\nstates of continuous variable systems.",
