Uniqueness of null-local modular flow
Gautam Satishchandran, Jonathan Sorce
In arXiv:2306.01837, it was conjectured that one can engineer a large class of quantum field theory states for which the modular flow on a spacelike slice is "instantaneously local…
Continuum canonical purifications
Jonathan Sorce
We construct and characterize canonical purifications for general algebraic states, extending prior constructions by Woronowicz and by Dutta/Faulkner to general quantum theories. G…
A classical model for semiclassical state-counting
Jonathan Sorce
In the type II von Neumann algebras that appear in semiclassical gravity, all states have infinite entropy, but entropy differences are uniquely defined. Akers and I have shown tha…
Relative state-counting for semiclassical black holes
Chris Akers, Jonathan Sorce
It has been shown that entropy differences between certain states of perturbative quantum gravity can be computed without specifying an ultraviolet completion. This is analogous to…
Analyticity and the Unruh effect: a study of local modular flow
Jonathan Sorce
The Unruh effect can be formulated as the statement that the Minkowski vacuum in a Rindler wedge has a boost as its modular flow. In recent years, other examples of states with geo…
Relational bulk reconstruction from modular flow
Onkar Parrikar, Harshit Rajgadia, Vivek Singh +1
The entanglement wedge reconstruction paradigm in AdS/CFT states that for a bulk qudit within the entanglement wedge of a boundary subregion , operators acting on the bulk…
An intuitive construction of modular flow
Jonathan Sorce
The theory of modular flow has proved extremely useful for applying thermodynamic reasoning to out-of-equilibrium states in quantum field theory. However, the standard proofs of th…
A short proof of Tomita's theorem
Jonathan Sorce
Tomita-Takesaki theory associates a positive operator called the "modular operator" with a von Neumann algebra and a cyclic-separating vector. Tomita's theorem says that the unitar…
Generalized entropy for general subregions in quantum gravity
Kristan Jensen, Jonathan Sorce, Antony Speranza
We consider quantum algebras of observables associated with subregions in theories of Einstein gravity coupled to matter in the limit. When the subregion is spat…
Reflected entropy is not a correlation measure
Patrick Hayden, Marius Lemm, Jonathan Sorce
By explicit counterexample, we show that the "reflected entropy" defined by Dutta and Faulkner is not monotonically decreasing under partial trace, and so is not a measure of physi…
Notes on the type classification of von Neumann algebras
Jonathan Sorce
These notes provide an explanation of the type classification of von Neumann algebras, which has made many appearances in recent work on entanglement in quantum field theory and qu…
The connected wedge theorem and its consequences
Alex May, Jonathan Sorce, Beni Yoshida
In the AdS/CFT correspondence, bulk causal structure has consequences for boundary entanglement. In quantum information science, causal structures can be replaced by distributed en…
Approximate Petz recovery from the geometry of density operators
Sam Cree, Jonathan Sorce
We derive a new bound on the effectiveness of the Petz map as a universal recovery channel in approximate quantum error correction using the second sandwiched Rényi relative entrop…
A canonical Hamiltonian for open quantum systems
Patrick Hayden, Jonathan Sorce
If an open quantum system is initially uncorrelated from its environment, then its dynamics can be written in terms of a Lindblad-form master equation. The master equation is divid…
The Markov gap for geometric reflected entropy
Patrick Hayden, Onkar Parrikar, Jonathan Sorce
The reflected entropy of a density matrix is a bipartite correlation measure lower-bounded by the quantum mutual information . In holographic states sat…
Geometric conditions for saturating the data processing inequality
Sam Cree, Jonathan Sorce
The data processing inequality (DPI) is a scalar inequality satisfied by distinguishability measures on density matrices. For some distinguishability measures, saturation of the sc…
Holographic scattering requires a connected entanglement wedge
Alex May, Geoff Penington, Jonathan Sorce
In AdS/CFT, there can exist local 2-to-2 bulk scattering processes even when local scattering is not possible on the boundary; these have previously been studied in connection with…
Large- phase transitions in holographic mutual information
Sean Colin-Ellerin, Veronika E. Hubeny, Benjamin E. Niehoff +1
In the AdS/CFT correspondence, the entanglement entropy of subregions in the boundary CFT is conjectured to be dual to the area of a bulk extremal surface at leading order in …
Holographic entanglement entropy is cutoff-covariant
Jonathan Sorce
In the AdS/CFT correspondence, it is often convenient to regulate infinite quantities in asymptotically anti-de Sitter spacetimes by introducing a sharp cutoff in a radial coordina…
Holographic Tensor Networks in Full AdS/CFT
Ning Bao, Geoffrey Penington, Jonathan Sorce +1
We present a general procedure for constructing tensor networks for geometric states in the Anti-de Sitter/Conformal Field Theory (AdS/CFT) correspondence. Given a state in a large…
Beyond Toy Models: Distilling Tensor Networks in Full AdS/CFT
Ning Bao, Geoffrey Penington, Jonathan Sorce +1
We present a general procedure for constructing tensor networks that accurately reproduce holographic states in conformal field theories (CFTs). Given a state in a large- CFT wi…
