Explore the fascinating intersection of black holes and quantum computing in this comprehensive lecture by Leonard Susskind from Stanford University. Delve into how black holes challenge the Quantum-Extended Church-Turing Thesis (QECTT) and discover how horizon properties ultimately rescue it. Gain insights into the complexity of extracting information from behind black hole horizons. Follow along as Susskind breaks down complex concepts, making them accessible to a broad audience. After the main presentation, engage with a panel discussion featuring renowned experts Scott Aaronson, Geoffrey Penington, Edward Witten, and moderator Umesh Vazirani, who further explore the implications of this groundbreaking research.
