Explore the intricacies of the information paradox in AdS/CFT and its resolution through entanglement wedge reconstruction in this comprehensive lecture. Delve into topics such as evaporating black holes, quantum extremal surfaces, and the Page curve. Examine the firewall paradox, state dependence, and the mechanisms of information retrieval from black holes. Gain insights into holographic approaches using the replica trick and compare replica entropy with semiclassical entropy. Investigate a simple toy model to better understand these complex concepts in quantum gravity and holography.
