Description

The entropy of von-Neumann can be computed directly by describing the density matrix of the associated system. For black holes however, it is rather difficult to evaluate this entropy because before all else we must have a quantum formulation of this gravitational system. We outline the derivation of a gravitational fine-grained entropy using a quantum extremal surface that extremizes the generalized entropy, i.e., the sum of area and bulk entanglement entropy, following the Page curve. We illustrate this formulation for the AdS/CFT case and calculate the corresponding fine-grained entropy.
