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…
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…
Estimation of pulsed driven qubit parameters via quantum Fisher information
N. Metwally, S. S. Hassan
We estimate the initial weight and phase parameters ( of a single qubit system initially prepared in the coherent state and interacts with three different shape…
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…
Enhancing entanglement, local and non-local information of accelerated two-qubit and two- qutrit systems via weak-reverse measurements
Nasser Metwally
The possibility of recovering and protecting the entanglement of accelerated 2-qubit and 2-qutrit systems is discussed using weak-reverse measurements. The accelerated partial enta…
Entanglement Routers via Wireless Quantum Network Based on Arbitrary Two Qubit Systems
N. Metwally
A wireless quantum network is generated between multi-hop, where each hop consists of two entangled nodes. These nodes share a finite number of entangled two qubit systems randomly…
