Abstract:

 Quantum optics is a quantum interpretation of phenomenon involving light and its behavior against the interaction with matter. By the 1980s the theorists realized the possible interaction between single atoms and single modes of the electromagnetic field.  The study involving light-matter interactions become very popular among scientists theoretically as well as experimentally due to its advantageous application for future quantum technologies.

 Quantum information science (QIS) is a rapidly developing field whose significance ranges from fundamental issues in the foundations of quantum theory to new state-of-the-art methods for the treatment and transmission of information. QIS requires advanced technical and typical tools of classical information theory, classical and quantum statistical mechanics and quantum optics.  The study of quantum correlations properties of large class of quantum systems for pure and mixed states by introducing several techniques such as ordinary and nonlinear coherent states, power-law potentials, ideal and real lasers, deformed systems using q-entropies, interaction field-atom in cavity system, micro cavities systems, beam splitter, etc.
