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…
A new characterization of the holographic entropy cone
Guglielmo Grimaldi, Matthew Headrick, Veronika E. Hubeny
Entanglement entropies computed using the holographic Ryu-Takayanagi formula are known to obey an infinite set of linear inequalities, which define the so-called RT entropy cone. T…
Combinatorial properties of holographic entropy inequalities
Guglielmo Grimaldi, Matthew Headrick, Veronika E. Hubeny +1
A holographic entropy inequality (HEI) is a linear inequality obeyed by Ryu-Takayanagi holographic entanglement entropies, or equivalently by the minimum cut function on weighted g…
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…
Testing holographic entropy inequalities in 2+1 dimensions
Brianna Grado-White, Guglielmo Grimaldi, Matthew Headrick +1
We address the question of whether holographic entropy inequalities obeyed in static states (by the RT formula) are always obeyed in time-dependent states (by the HRT formula), foc…
