We formulate a version of the information paradox in de Sitter spacetime and show that it is
solved by the emergence of entanglement islands in the context of the De Sitter/de Sitter …

We study the holographic dual of a topological symmetry operator in the context of the
AdS/CFT correspondence. Symmetry operators arise from topological field theories …

We calculate logarithmic negativity, a quantum entanglement measure for mixed quantum
states, in quantum error-correcting codes and find it to equal the minimal cross sectional …

A bstract The\(T\overline {T}\) deformation of a conformal field theory has a dual description
as a cutoff AdS 3 spacetime, at least at the level of pure 3d gravity. We generalize this …

A bstract 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-N …

A bstract We study Renyi entropies S n in quantum error correcting codes and compare the
answer to the cosmic brane prescription for computing\({\tilde {S}} _n\equiv {n}^ 2 {\partial} …

A bstract We initiate a study of subregion dualities, entropy, and redundant encoding of bulk
points in holographic theories deformed by\(T\overline {T}\) and its generalizations. This …

A bstract We argue that holographic CFT states require a large amount of tripartite
entanglement, in contrast to the conjecture that their entanglement is mostly bipartite. Our …

We explore a conformal field theoretic interpretation of the holographic entanglement of
purification, which is defined as the minimal area of the entanglement wedge cross section …

A bstract We introduce a new information-theoretic measure of multipartite correlations Δ P,
by generalizing the entanglement of purification to multipartite states. We provide proofs of …
