Relative entropy of entanglement and tripartite minimal surface
Takato Mori, Beni Yoshida
We propose a holographic dual of the relative entropy of entanglement for a boundary tripartition . Our proposal is that, at the leading order, \begin{align} E_R(ρ_{AB}) = \…
Informational and algebraic renormalization group
Takato Mori, Teruaki Nagasawa
Renormalization group (RG) is a core concept in physics from statistical mechanics to quantum field theory, yet its schemes differ widely between field theory and many-body physics…
Relative entropy of entanglement of Haar random states
Takato Mori, Beni Yoshida
We determine the relative entropy of entanglement of a bipartite mixed state obtained by tracing out one subsystem of a tripartite Haar-random pure state …
Rethinking quantum information in gravity and fields
Kanato Goto, Yuta Hamada, Kohtaro Kato +6
This paper presents a curated selection of research questions at the intersection of quantum gravity and quantum information, chosen to highlight issues that we regard as particula…
Baby universe as logical qubits: information recovery in random encoding
Takato Mori, Beni Yoshida
We revisit whether a semiclassical closed baby universe in AdS/CFT necessarily possess a trivial one-dimensional Hilbert space or may instead carry a large entropy. Recent results…
Entanglement sharing schemes
Zahra Khanian, Dongjin Lee, Debbie Leung +7
We ask how quantum correlations can be distributed among many subsystems. To address this, we define entanglement sharing schemes (ESS) where certain pairs of subsystems allow enta…
Quantum correlation beyond entanglement: Holographic discord and multipartite generalizations
Takato Mori
While entanglement is a cornerstone of quantum theory and holography, quantum correlations arising from superposition, such as quantum discord, offer a broader perspective that has…
Tripartite Haar random state has no bipartite entanglement
Zhi Li, Takato Mori, Beni Yoshida
We show that no EPR-like bipartite entanglement can be distilled from a tripartite Haar random state by local unitaries or local operations when each subsystem $A…
Does connected wedge imply distillable entanglement?
Takato Mori, Beni Yoshida
The Ryu-Takayanagi formula predicts that two boundary subsystems and can exhibit large mutual information even when they are spatially disconnected on the boundary…
Horizon causality from holographic scattering in asymptotically dS
Victor Franken, Takato Mori
In the AdS/CFT correspondence, a direct scattering in the bulk may not have a local boundary analog. A nonlocal implementation on the boundary requires mutual informatio…
