Analytically Continuing the Randomized Measurement Toolbox
Akash Vijay, Ayush Raj, Jonah Kudler-Flam +3
We develop a framework for extracting non-polynomial analytic functions of density matrices in randomized measurement experiments by a method of analytical continuation. A central…
Logarithmic negativity typically equals exact entanglement cost
Bowen Ouyang, Jonah Kudler-Flam
Quantum entanglement plays a leading role in modern understanding of physical systems, from quantum phases of matter to quantum gravity. In quantum information theory, one seeks op…
Wormholes and Averaging over N
Jonah Kudler-Flam, Edward Witten
The gravitational path integral produces an asymptotic expansion in , a fact which is puzzling in the case of observables that are expected to fluctuate wildly. Wormholes appe…
Generalized Entropy is von Neumann Entropy II: The complete symmetry group and edge modes
Marc S. Klinger, Jonah Kudler-Flam, Gautam Satishchandran
We consider the algebra of observables of perturbative quantum gravity in the exterior of a stationary black hole or the static patch of de Sitter spacetime. It was previously argu…
Stringy algebras, stretched horizons, and quantum-connected wormholes
Aidan Herderschee, Jonah Kudler-Flam
While the supergravity limit of AdS/CFT has been extensively explored, the regime in which stringy dynamics dominate, characterized by the emergence of an infinite tower of higher-…
Emergent Mixed States for Baby Universes and Black Holes
Jonah Kudler-Flam, Edward Witten
We examine the behavior of sequences of states in the large limit of AdS/CFT duality in cases in which the bulk duals involve baby universes or black holes. Such sequences gene…
