A treatment of the quantum partial entropies in the atom-field interaction with a class of Schrodinger cat states
A. -S. F. Obada, H. A. Hessian, Mahmoud Abdel-Aty
This communication is an enquiry into the circumstances under which entropy and subentropy methods can give an answer to the question of quantum entanglement in the composite state…

Entanglement manipulation for mixed states in a multilevel atom interacting with a cavity field
Mahmoud Abdel-Aty, M. R. B. Wahiddin, A. -S. F. Obada
We derive an explicit formula for an entanglement measure of mixed quantum states in a multi-level atom interacting with a cavity field within the framework of the quantum mutual e…
