We review recent progress on the information paradox. We explain why exponentially small
correlations in the radiation emitted by a black hole are sufficient to resolve the original …

These lectures give an introduction to the quantum physics of black holes, including recent
developments based on quantum information theory such as the firewall paradox and its …

A bstract The black hole information problem has motivated many proposals for new
physics. One idea, known as state-dependence, is that quantum mechanics must be …

We review the paradox of low energy excitations of a black hole in anti–de Sitter space
(AdS). An appropriately chosen unitary operator in the boundary theory can create a locally …

A bstract The AMPS paradox challenges black hole complementarity by apparently
constructing a way for an observer to bring information from the outside of the black hole into …

We formulate certain inequalities for the geometric quantities characterizing causal
diamonds in curved and Minkowski spacetimes. These inequalities involve the redshift factor …

Making use of the emergence of an entangling gate from the Mayer Vietoris maps
generating a torus and employing the correspondence between quantum error correction …

This thesis is an exposition of some of the work I conducted as part of my PhD. In broad
terms, the subject of interest is quantum gravity—specifically, as alluded in the somewhat …

Typical cosmological states have structure, obey to very good approximation the laws of
classical physics on large scales, and are far from equilibrium. Typical quantummechanical …

This thesis is an exposition of some of the research that I carried out during my doctoral
studies. Broadly speaking, my research focused on how fundamental subjects such as …
