Abstract: |
One of the most important discoveries in theoretical physics in the late 20th century is the thermodynamics of black holes, especially the fact that the entropy of a black hole is given by its horizon area. This has led to the extraordinary concept of holography in quantum gravity, which is elegantly illustrated by the celebrated AdS/CFT correspondence. On the other hand, the problem associated with quantum information in a process involving black holes, first observed by Hawking, has confused theoretical physicists working in this area for decades. In this talk, I review the current status of the black hole information problem and present the latest progress in quantum gravity which has taken place in analyzing this decades-old problem. |
