The behavior of the atomic occupation probabilities of the upper and lower levels gained by a two-ion system interacting with a laser field is investigated. At a fixed time the immediate relations of the populations are examined against several physical parameters. It is observed that for some intermediate ranges of the detuning parameters and the coupling strength, the presence of ... Read more

Based on exact quantum dynamics of a single four-level atom strongly coupled to a cavity field mode and driven by a coherent laser field, we investigate quantum mutual entropy as a measure of the amount of total correlations. Through the analysis of the dynamic of the total correlation, we show that under the influence of the decoherence, the total correlation ... Read more

Engineering entanglement in a single trapped ion interacting with a laser field Read more

Trapped and laser-cooled ions are increasingly used for a variety of modern high-precision experiments, frequency standard applications and quantum information processing. Therefore, in this communication we present a comprehensive analysis of the pattern of information entropy arising in the time evolution of an ion interacting with a laser field. A general analytic approach is proposed for a three-level trapped-ion system ... Read more

This contribution explores the perceptions, ideas and understanding about the phase entropy of the ion-field interaction. Here we discuss the interaction between a single qubit (trapped ion) and a single laser field. We construct the explicit solution of this problem. Employing an obtained exact solution of the problem, significant features of the phase entropy in the context of the measure ... Read more
