Abstract: 

In these lectures I will describe the ideas developed in 1905.08255, 1905.08762, 1908.10996, 1910.11077, 1911.12333, 1911.11977.

Lec 1 - I will start a short description of black hole solution in Jackiw-Teitelboim gravity. In order to be precise, I will stick to the model considered in (1910.11077) to study the black holes information loss problem. I will describe the construction of this model and present a naive computation of the entanglement entropy (EE) of the radiation (with the black hole). This computation contradicts unitarity in the bulk and is the statement of the information problem.

Lec 2 - I will start with a brief discussion of entanglement wedge reconstruction conjecture and introduce the quantum Ryu-Takayanagi (QRT) prescription for the computation of the EE holographically. Understanding this model from an AdS_2/CFT_1 perspective and analysing the entanglement wedge of the radiation tells us that some part of the interior of the black hole is actually encoded in the radiation. This gives rise to the 'Island prescription' for the computation of the EE of the radiation (with the blak hole) which reproduces a unitary result.

Lec 3 - I will motivate the 'Island prescription' from a perspective of AdS_3/CFT_2. We will also discuss the origin of the 'Island prescription' in the replica wormholes which arise naturally in the computation of the EE via replica trick (1911.12333)

Lec 4 - Quantum error correction from 1911.11977 and other related topics.
