Description
Summary:Black holes evolve by evaporation of their event horizon. While this process is believed to be unitary, there is no consensus on the recovery of information in black hole entropy. A missing link is a quantum of information in black hole evaporation. Distinct from Hawking radiation, we identify evaporation in entangled pairs by P 2 topology of the event horizon consistent with the Bekenstein–Hawking entropy in a uniformly spaced horizon area. It derives by continuation of P 2 in Rindler spacetime prior to gravitational collapse, subject to a tight correlation of the fundamental frequency of quasi-normal-mode ringing in gravitational and electromagnetic radiation. Information extraction from entangled pairs by detecting one over the surface spanned by three faces of a large cube carries a quantum of information 2 k B log 3 upon including measurement of spin.
