Title: Quantum Error Correction and Recovery Maps/Protocols in Quantum Black Holes

Abstract: The Hayden-Preskill thought experiment is a type of quantum error correction. In this talk, I will review and discuss quantum error correction perspectives of quantum black holes related to the Hayden-Preskill protocol. In particular, based on work in progress with Tomonori Ugajin (YITP) and Yasuaki Nakayama (Kyoto), I will discuss mainly three recovery maps/protocols(Petz recovery map, Petz lite, and the Kitaev-Yoshida protocol) and also the relation among them. If there is time, I will also discuss another perspective of their recovery maps in the SYK Model.
