In these lectures I give an introduction to the quantum physics of black holes, including recent developments based on quantum information theory such as the rewall paradox and its various cousins. I also give an introduction to holography and the AdS/CFT correspondence, focusing on those aspects which are relevant for the black hole information problem. 

Modave Lectures on Quantum Information: An Introduction to Channels and Applications to Black Holes and AdS/CFT

These notes introduce a handful of core ideas from quantum information science that figure prominently in modern research on quantum gravity, including the most general physically-reasonable map between quantum states and between operators on Hilbert space.

Quantum Black Holes

This article is divided into three parts. First, a systematic derivation of the Hawking radiation is given in three different ways. The information loss problem is then discussed in great detail. The

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 theory to have a

Hawking Radiation Is Pure

Information loss paradox is still a challenging problem in theoretical physics. In this essay, for statics BTZ black holes and Schwarzschild black holes, we propose a simple solution based on the

TASI Lectures on the Emergence of the Bulk in AdS/CFT

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 theory to have a

The aim of this paper is to give an overview to nonspecialists of recent arguments from fundamental physics in favor and disfavor of quantum corrections to black hole horizons. I will mainly discuss

Black hole information and Reeh-Schlieder theorem

The Reeh-Schlieder theorem, with the time-slice axiom of quantum field theory, may be used to recover the information which falls into a black hole. Analyticity of quantum fields in states with

The Incomplete Semiclassical Analysis of the Black Hole Information Paradox and its Completion via Entanglement of Radiation and Quantum Gravity Degrees of Freedom

We argue that the semiclassical analysis of the black hole information paradox is incomplete and has to be completed by an explicit entanglement of matter and quantum gravity degrees of freedom. We

Trouble in Paradox

: Recent developments in holography have suggested a potential resolution to the black hole information paradox within the context of gravitational effective field theory. We emphasize the non-local

Black Holes in String Theory

Black holes are the hydrogen atoms of quantum gravity. For instance solving the information loss paradox will likely require a deep understanding of how the long-sought quantum gravity theory works.



Some speculations about black hole entropy in string theory

The classical Bekenstein entropy of a black hole is argued to arise from configurations of strings with ends which are frozen on the horizon. Quantum corrections to this entropy are probably finite

Black hole interior in the holographic correspondence and the information paradox.

This work describes a remarkably simple construction of certain kinds of operators in the conformal field theory (CFT) on a given state of the CFT, which leads to a smooth horizon, addresses the strong subadditivity paradox, while preserving locality within effective field theory.

Comments on black holes in string theory

A very brief review is given of some of the developments leading to our current understanding of black holes in string theory. This is followed by a discussion of two possible misconceptions in this

Gauge-gravity duality and the black hole interior.

The Einstein-R Rosen=Einstein-Podolsky-Rosen conjecture of Maldacena and Susskind is addressed, arguing that the correlations in generic highly entangled states cannot be geometrized as a smooth wormhole.

Eternal black holes in anti-de Sitter

We propose a dual non-perturbative description for maximally extended Schwarzschild Anti-de-Sitter spacetimes. The description involves two copies of the conformal field theory associated to the AdS

Behind the Horizon in AdS/CFT

We extend the recent proposal of Papadodimas and Raju of a CFT construction of operators inside the black hole interior to arbitrary non-maximally mixed states. Our construction builds on the general

An Introduction to Black Holes, Information And The String Theory Revolution: The Holographic Universe

Over the last decade the physics of black holes has been revolutionized by developments that grew out of Jacob Bekenstein's realization that black holes have entropy. Stephen Hawking raised profound

The Black Hole Interior in AdS/CFT and the Information Paradox

We show that, within the AdS/CFT correspondence, recent formulations of the information paradox can be reduced to a question about the existence of certain kinds of operators in the CFT. We describe

Information loss in black holes

The question of whether information is lost in black holes is investigated using Euclidean path integrals. The formation and evaporation of black holes is regarded as a scattering problem with all
