M. Schiffer, RECOVERING INFORMATION BORNE BY QUANTA THAT CROSSED THE BLACK-HOLE EVENT HORIZON, General relativity and gravitation, 26(5), 1994, pp. 469-476
In this essay we discuss how the statistics of quantum particles, name
ly, stimulated emission for bosons and the exclusion principle for fer
mions, provide mechanisms for correlating the radiations impinging and
emanating from a black hole. In either case, the information original
ly borne by the incoming radiation that is partially transferred to th
e outging radiation is estimated within the framework of communication
theory.
