Generalized von Neumann Mutual Information of a Single Trapped Ion Interacting with a Laser Field

摘要

In this communication, we present a generalization of the von Neumann mutual information in the context of Tsallis' nonextensive statistics. The measure of information content of ionic state due to ion-laser interaction in a single trapped ion is discussed. Important changes occur in the generalized mutual information, which measures the degree of entanglement, depending on the entropic index. During the transition from collapse to revival and vice-versa we have minimum' degree of entanglement value.
