Exchanging quantum correlations and non-local information between three qubit-syatem
F. Ebrahiam, N. Metwally
The possibility of exchanging the quantum correlations and the non-local information between three qubits interact directly or indirectly via Dzyaloshinskii-Moriya (DM)is discussed…
The orthogonality speed of two-qubit state interacts locally with spin chain in the presence of Dzyaloshinsky-Moriya interaction
D. A. M. Abo-Kahla, M. Y. Abd-Rabbou, N. Metwally
The orthogonality time is examined for different initial states settings interacting locally with different types of spin interaction: , Ising and anisotropic models. It is sho…
Restrain the losses of the entanglement and the non-local advantage of quantum coherence for accelerated quantum systems
A. R. Mohammed, T. M. El-Shahat, N. Metwally
We examined the possibility of recovering the losses of entanglement and the non-local advantage by using the local symmetric operations. The improvement efficiency may be increase…
Suppressing local enviromental noise in non clasical communication
N. Metwally, A. -S. Obada
We have modified the work
Some entanglement features of three-atoms Tavis-Cummings model: Cooperative case
M. Youssef, A. -S. F. Obada, N. Metwally
In this paper we consider a system of identical three two-level atoms interacting at resonance with a single-mode of the quantized field in a lossless cavity. The initial cavity fi…
Dynamics of impurity, local and non-local information for two non identical qubits
N. Metwally, M. Abdel-Aty, M. Sebawe Abdall
From the separability point of view the problem of two atoms interact with a single cavity mode is investigated. The density matrix is calculated and used to discuss the entangleme…
