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…
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 quantum marginal independence problem
Sergio Hernández-Cuenca, Veronika E. Hubeny, Mukund Rangamani +1
We investigate whether the presence or absence of correlations between subsystems of an N-partite quantum system is solely constrained by the non-negativity and monotonicity of mut…
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…
Gravity from micro-equilibration
Veronika E. Hubeny, Massimiliano Rota
We suggest a mechanism for the emergence of classical dynamical spacetime from an underlying quantum gravitational system. This is an example of a more general process, which we na…
Maximin is Not Enough
Massimiliano Rota, Sean J. Weinberg
The RT formula for static spacetimes arising in the AdS/CFT correspondence satisfies inequalities that are not yet proven in the case of the HRT formula, which applies to general d…
Quantum information/entanglement transfer rates between subsystems
Steven B. Giddings, Massimiliano Rota
The size of quantum information -- or entanglement -- transfer rates between subsystems is a generic question in problems ranging from decoherence in quantum computation and sensin…
Handlebody phases and the polyhedrality of the holographic entropy cone
Donald Marolf, Massimiliano Rota, Jason Wien
The notion of a holographic entropy cone has recently been introduced and it has been proven that this cone is polyhedral. However, the original definition was fully geometric and…
Tripartite information of highly entangled states
Massimiliano Rota
Holographic systems require monogamous mutual information for validity of semiclassical geometry. This is encoded by the sign of the tripartite information (). We investigate t…
Positivity, negativity, and entanglement
Eric Perlmutter, Mukund Rangamani, Massimiliano Rota
We explore properties of the universal terms in the entanglement entropy and logarithmic negativity in 4d CFTs, aiming to clarify the ways in which they behave like the analogous e…
Entanglement structures in qubit systems
Mukund Rangamani, Massimiliano Rota
Using measures of entanglement such as negativity and tangles we provide a detailed analysis of entanglement structures in pure states of non-interacting qubits. The motivation for…
Comments on Entanglement Negativity in Holographic Field Theories
Mukund Rangamani, Massimiliano Rota
We explore entanglement negativity, a measure of the distillable entanglement contained in a quantum state, in relativistic field theories in various dimensions. We first give a ge…
Quantum Channels in Quantum Gravity
Mukund Rangamani, Massimiliano Rota
The black hole final state proposal implements manifest unitarity in the process of black hole formation and evaporation in quantum gravity, by postulating a unique final state bou…
