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…
A gap between holographic and quantum mechanical extreme rays of the subadditivity cone
Temple He, Veronika E. Hubeny, Massimiliano Rota
We show via explicit construction that for six or more parties, there exist extreme rays of the subadditivity cone that can be realized by quantum states, but not by holographic st…
On the relation between the subadditivity cone and the quantum entropy cone
Temple He, Veronika E. Hubeny, Massimiliano Rota
Given a multipartite quantum system, what are the possible ways to impose mutual independence among some subsystems, and the presence of correlations among others, such that there…
The holographic entropy cone from marginal independence
Sergio Hernández-Cuenca, Veronika E. Hubeny, Massimiliano Rota
The holographic entropy cone characterizes the relations between entanglement entropies for a spatial partitioning of the boundary spacetime of a holographic CFT in any state descr…
The holographic entropy arrangement
Veronika E. Hubeny, Mukund Rangamani, Massimiliano Rota
We develop a convenient framework for characterizing multipartite entanglement in composite systems, based on relations between entropies of various subsystems. This continues the…
