On the construction of graph models realizing given entropy vectors
Veronika E. Hubeny, Massimiliano Rota
We present an efficient algorithm for the construction of a holographic simple tree graph model that realizes a given entropy vector, subject to a specific ``chordality'' condition…

Correlation hypergraph: a new representation of a quantum marginal independence pattern
Veronika E. Hubeny, Massimiliano Rota
We continue the study of the quantum marginal independence problem, namely the question of which faces of the subadditivity cone are achievable by quantum states. We introduce a ne…

Algorithmic construction of SSA-compatible extreme rays of the subadditivity cone and the solution
Temple He, Veronika E. Hubeny, Massimiliano Rota
We compute the set of all extreme rays of the 6-party subadditivity cone that are compatible with strong subadditivity. In total, we identify 208 new (genuine 6-party) orbits, 52 o…
