Quantum information in holographic duality

B Chen, B Czech, ZZ Wang - Reports on Progress in Physics, 2022 - iopscience.iop.org
We give a pedagogical review of how concepts from quantum information theory build up
the gravitational side of the anti-de Sitter/conformal field theory correspondence. The review …

Holographic entropy inequalities and multipartite entanglement

S Hernández-Cuenca, VE Hubeny, HF Jia - Journal of High Energy …, 2024 - Springer
A bstract We study holographic entropy inequalities and their structural properties by making
use of a judicious grouping of terms into certain multipartite information quantities. This …

Entropy cones and entanglement evolution for Dicke states

W Munizzi, HJ Schnitzer - Physical Review A, 2024 - APS
The N-qubit Dicke states| D k N〉, of Hamming weight k, are a class of entangled states
which play an important role in quantum algorithm optimization. We present a general …

Holographic entropy inequalities and the topology of entanglement wedge nesting

B Czech, S Shuai, Y Wang, D Zhang - Physical Review D, 2024 - APS
We prove two new infinite families of holographic entropy inequalities. A key tool is a
graphical arrangement of terms of inequalities that is based on entanglement wedge …

Holographic cone of average entropies

B Czech, S Shuai - Communications Physics, 2022 - nature.com
The holographic entropy cone identifies entanglement entropies of field theory regions,
which are consistent with representing semiclassical spacetimes under gauge/gravity …

Perfect tensor hyperthreads

J Harper - Journal of High Energy Physics, 2022 - Springer
A bstract Bit threads, a dual description of the Ryu-Takyanagi formula for holographic
entanglement entropy (EE), can be interpreted as a distillation of the quantum information to …

A holographic inequality for N= 7 regions

B Czech, Y Wang - Journal of High Energy Physics, 2023 - Springer
A bstract In holographic duality, boundary states that have semiclassical bulk duals must
obey inequalities, which bound their subsystems' von Neumann entropies. Hitherto known …

Beyond the Holographic Entropy Cone via Cycle Flows

T He, S Hernández-Cuenca, C Keeler - Communications in Mathematical …, 2024 - Springer
Motivated by bit threads, we introduce a new prescription for computing entropy vectors
outside the holographic entropy cone. By utilizing cycle flows on directed graphs, we show …

[HTML][HTML] Deriving three-outcome permutationally invariant bell inequalities

A Aloy, G Müller-Rigat, J Tura, M Fadel - Entropy, 2024 - mdpi.com
We present strategies to derive Bell inequalities valid for systems composed of many three-
level parties. This scenario is formalized by a Bell experiment with N observers, each of …

A framework for generalizing toric inequalities for holographic entanglement entropy

N Bao, K Furuya, J Naskar - Journal of High Energy Physics, 2024 - Springer
A bstract We conjecture a multi-parameter generalization of the toric inequalities of [1]. We
then extend their proof methods for the generalized toric inequalities in two ways. The first …
