    "abstract": "We present an abstract formulation of the so-called Innsbruck-Hannover\nprogramme that investigates quantum correlations and entanglement in terms of\nconvex sets. We present a unified description of optimal decompositions of\nquantum states and the optimization of witness operators that detect whether a\ngiven state belongs to a given convex set. We illustrate the abstract\nformulation with several examples, and discuss relations between optimal\nentanglement witnesses and n-copy non-distillable states with non-positive\npartial transpose.",
