DESCRIPTION:Title: <a href="https://researchseminars.org/talk/QASTM/22/">T
 he black hole information paradox</a>\nby Vijay Balasubramanian (Departmen
 t of Physics and Astronomy\,  University of Pennsylvania School of Arts an
 d Sciences\, Philadelphia\, USA) as part of Quantum Aspects of Space-Time 
 and Matter\n\n\nAbstract\nFor nearly half a century\, physicists have aske
 d whether and how we can recover information falling into black holes in o
 rder 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 rol
 e of chaos in scrambling information into the microstates\; (d) explaining
  the role of quantum entanglement in information encoding by black holes a
 nd by Hawking radiation\;  (e) understanding geometrization of information
  in gravity\; and\, finally\, (f) uncovering connections with basic proble
 ms in information theory\,  quantum computation\, and complexity theory.\n
