The black hole information paradox

Abstract: For nearly half a century, physicists have asked whether and how we can recover information falling into black holes in order to guarantee the unitarity of quantum physics. In this talk, I will review progress we have made towards solving this puzzle. This progress includes: (a) identifying the quantum gravity microstates for some black holes; (b) showing that information about the microstates is available, but difficult to detect, outside the black hole; (c) identifying the role of chaos in scrambling information into the microstates; (d) explaining the role of quantum entanglement in information encoding by black holes and by Hawking radiation; (e) understanding geometrization of information in gravity; and, finally, (f) uncovering connections with basic problems in information theory, quantum computation, and complexity theory.
