Quantum correlations between each qubit in a two-atom system and the environment in terms of interatomic distance
K. Berrada, F. F. Fanchini, S. Abdel-Khalek
The quantum correlations between a qubit and its environment are described quantitatively in terms of interatomic distance. Specifically, considering a realistic system of two two-…

Dynamics of the intensity-dependent Jaynes-Cummings model analyzed via Fisher information
S. Abdel-Khalek, A. Plastino, A-S F. Obada
The dynamics of the Buck and Sukumar model [B. Buck and C.V. Sukumar, Phys. Lett. A 81 (1981) 132] are investigated using different semi-classical information-theory tools. Interes…
