Abstract:

Unitarity is required by quantum mechanics for the dynamics of any closed systems, i.e., information is conserved for closed systems. The black hole information loss conflicts to the unitarity, which indicates the impossibility of unifying quantum mechanics with gravity. In this paper, we review the origin of the puzzle and the possible solutions.
