Detraction of decoherence that arises from acceleration process
M. Y. Abd-Rabbou, S. I. Ali, N. Metwally
The possibility of detracting the decoherence due to the acceleration process of the two-qutrit system is investigated, where we examined the behaviour of the relative entropy and…
Decoherence and quantum steering of accelerated qubit-qutrit system
M. Y. Abd-Rabbou, N. Metwally, M. M. A. Ahmed +1
The bidirectional steerability between different-size subsystems is discussed for a single parameter accelerated qubit-qutrit system. The decoherence due to the mixing and accelera…
Wigner function of noisy accelerated two-qubit system
M. Y. Abd-Rabbou, N. Metwally, M. M. A. Ahmed +1
In this manuscript, the behavior of the Wigner function of accelerated and non-accelerated two qubit system passing through different noisy channels is discussed. The decoherence o…
Fisher information of a single qubit interacts with a spin-qubit in the presence of a magnetic field
N. Metwally
In this contribution, quantum Fisher information is utilized to estimate the parameters of a central qubit interacting with a single-spin qubit. The effect of the longitudinal, tra…
Estimation of teleported and gained parameters in a non-inertial frame
N. Metwally
We estimate the teleported and the gained parameters by means of Fisher information in a non-inertial frame. The sender and the receiver share an accelerated maximum or partial ent…
Long-lived entanglement with Pulsed-driven initially entangled qubit pair
N. Metwally, H. A. Batarfi, S. S. Hassan
The entanglement of different classes of initially entangled qubit pair is investigated in the presence of short laser pulses of rectangular and exponential shapes with either one…
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…
The quantum computational speed of a single Cooper Pair box
A. -S. F. Obada, D. A. M. Abo-Kahla, N. Metwally +1
The speed of computations is investigated by means of the orthogonality speed for a charged qubit interacting with a single cavity field prepared initially in a Fock state or Binom…
Enhancement of nonclassical properties of two qubits via deformed operators
N. Metwally, M. Sebawe Abdalla, M. Abdel-Aty
We explore the dynamics of two atoms interacting with a cavity field via deformed operators. Properties of the asymptotic regularization of entanglement measures proving, for examp…
Entangled states generation of two atoms interacting with a cavity field
F. N. M. Al-Showaikh, N. Metwally, M. Abdel-Aty
We classify different classes of entangled states arise in a two-qubit system. Some of these classes are of Bell's state types, while others are of the Werner's state types. The de…
