A bstract We propose a family of exactly solvable toy models for the AdS/CFT
correspondence based on a novel construction of quantum error-correcting codes with a …

We revisit two-dimensional holography with the Sachdev-Ye-Kitaev models in mind. Our
main result is to rewrite a generic theory of gravity near a two-dimensional anti-de Sitter …

I argue that a version of the quantum-corrected Ryu–Takayanagi formula holds in any
quantum error-correcting code. I present this result as a series of theorems of increasing …

These lectures review recent developments in our understanding of the emergence of local
bulk physics in AdS/CFT. The primary topics are sufficient conditions for a conformal field …

A bstract We study the reconstruction of bulk operators in the entanglement wedge in terms
of low energy operators localized in the respective boundary region. To leading order in N …

Black holes provide a window into the microscopic structure of spacetime in quantum
gravity. Recently the quantum information contained in Hawking radiation has been …

A bstract We argue that the degrees of freedom in a d-dimensional CFT can be reorganized
in an insightful way by studying observables on the moduli space of causal diamonds (or …

We explore a class of random tensor network models with “stabilizer” local tensors which we
name random stabilizer tensor networks (RSTNs). For RSTNs defined on a two-dimensional …

The low-energy subspace of a conformal field theory (CFT) can serve as a quantum error
correcting code, with important consequences in holography and quantum gravity. We …

A bstract We consider states of holographic conformal field theories constructed by adding
sources for local operators in the Euclidean path integral, with the aim of investigating the …
