Description
A generalization for the quantum information retrieval protocol recently illustrated by E. Verlinde and J. van der Heijden for evaporating black holes is provided for inclusions of type III von Neumann factors. The physical interest of such scenario arises in Quantum Field Theory, where local algebras are type III von Neumann algebras. The formula obtained can be easily interpreted in terms of the statistical dimension of super-selection sectors in the case of black holes undergoing charge evaporation, thanks to the index-statistics theorem, leading to a thermodynamic interpretation.
