Entanglement control of two-level atoms in dissipative cavities
Reyad Salah, Ahmed M. Farouk, Ahmed Farouk +2
An open quantum bipartite system consisting of two independent two-level atoms interacting non-linearly with a two-mode electromagnetic cavity field is investigated by proposing a…
New Design of Reversible Full Adder/Subtractor using gate
Rasha Montaser, Ahmed Younes, Mahmoud Abdel-Aty
Quantum computers require quantum processors. An important part of the processor of any computer is the arithmetic unit, which performs binary addition, subtraction, division and m…
Information under Lorentz transformation
N. Metwally, H. Eleuch, M. Abdel-Aty
A general form of a two-qubit system is obtained under the effect of Lorentz transformation. We investigate extensively some important classes in the context of quantum information…
A geometric approach to the distribution of quantum states in bipartite physical systems
J. Batle
Any set of pure states living in an given Hilbert space possesses a natural and unique metric --the Haar measure-- on the group of unitary matrices. However, there is no spe…
Skew Information for a single Cooper Pair Box interacts with a single cavity Mode
N. Metwally, A. Al-Mannai, M. Abdel-Aty
The dynamics of the skew information (SI) is investigated for a single Cooper Pair Box,CPB interacts with a single cavity mode. The effect of the cavity and CPB's parameters on the…
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-…
