Quantum mutual entropy for two-level ion in a q-analog trap

arXiv:quant-ph/0105060

Abstract

Quantum mutual entropy is used as a measure of information content of ionic state due to ion-laser interaction in a q-analog trap. The initial state of the system is a Schrodinger cat state. It is found that the partial mutual entropy is a good measure of the entanglement and purity of the ionic state at .
