John Preskill: Quantum information and spacetime (I) |
|
I will review how tools from quantum information theory are providing a fresh perspective on some of the deepest problems in particle physics and gravitation. The first lecture will be a brisk overview of the current status of fundamental physics, followed by a discussion of entanglement in quantum field theory and of the properties of quantum black holes. The second lecture will be an introduction to AdS/CFT duality in quantum gravity, emphasizing the emergence of spacetime from entanglement and the role of quantum error correction. I know it sounds scary, but I’m a physicist, so it will be perfectly safe.
