Title: Entanglement and nonextensive statistics
Author: Vidiella-Barranco, A
Abstract: It is presented a generalization of the von Neumann mutual information in the context of Tsallis' nonextensive statistics. As an example, entanglement between two (two-level) quantum subsystems is discussed. Important changes occur in the generalized mutual information, which measures the degree of entanglement, depending on the entropic index q. (C) 1999 Published by Elsevier Science B.V.
