Three Lectures on Complexity and Black Holes

Exploring the intersection of quantum complexity and black holes, this series of lectures delves into the relationship between complexity and the second law of thermodynamics. The first lecture introduces quantum complexity and its parallels with entropy, while the second examines how this complexity relates to black hole interiors and firewalls. The final lecture discusses the thermodynamics of complexity, highlighting "uncomplexity" as a valuable resource for computation and emphasizing the significance of "one clean qubit" in both computational and space-time contexts.
