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…
Maximum entangled states and quantum Teleportation via Single Cooper pair Box
N. Metwally, A. A. El-Amin
In this contribution, we study a single Cooper pair box interacts with a single cavity mode. We show the roles played by the detuning parameters and charged capacities on the degre…
Dynamics of Bloch vectors and the channel capacity of a non identical charged qubit pair
Nasser Metwally, Mahmoud Abdel-Aty
We have considered a system of two superconducting charge qubits capacitively coupled to a microwave resonator. The dynamics of the Bloch vectors are investigated for different reg…
Quantum deficits and correlations of two superconducting charge qubits
Nasser Metwally, Mahamoud Abde-Aty
Motivated by recent experiments [Pashkin et al. Nature, \textbf{421}, 823 (2003)] which showed coherent oscillations of two superconducting qubits system, we consider a system of t…
More Efficient Purifying scheme via Controlled- Controlled NOT Gate
Nasser Metwally, Abdel-Shafy F. Obada
A new modified version of the Oxford purification protocol is proposed. This version is based on the controlled-controlled NOT gate instead of controlled NOT in the original one. C…
Controlling the quantum computational speed
N. Metwally, M. Abdel-Aty, M. Sebawe Abdalla
The speed of quantum computation is investigated through the time evolution of the speed of the orthogonality. The external field components for classical treatment beside the detu…
