Quantum correlations and metrological advantage among Unruh-DeWitt detectors in de Sitter spacetime
Samira Elghaayda, Asad Ali, M. Y. Abd-Rabbou +2
A long-standing debate on Gibbons-Hawking (GH) decoherence centers on its unclear thermal nature. In this work, we investigate the robustness of quantum Fisher information (QFI) an…
Kitaev Quantum Batteries: Super-Extensive Scaling of Ergotropy in 1D Spin Chain
Asad Ali, Samira Elghaayda, Saif Al-Kuwari +7
We investigate the performance of a novel model based on a one-dimensional (1D) spin- Heisenberg quantum chain, also known as 1D Kitaev chain, as a working medium fo…
Entanglement-enhanced optimal quantum metrology
Muhammad Talha Rahim, Saif Al-Kuwari, Asad Ali
Quantum optimal control (QOC) schemes can be employed to enhance the sensitivity of quantum metrology (QM) protocols undergoing Markovian noise, which can limit their precision to…
Performance of a Superconducting Quantum Battery
Samira Elghaayda, Asad Ali, Saif Al-Kuwari +3
Finding a quantum battery model that demonstrates a quantum advantage while remaining feasible for experimental production is a considerable challenge. Here, a superconducting quan…
Magnetic Dipolar Quantum Battery with Spin-Orbit Coupling
Asad Ali, Samira Elghaayda, Saif Al-Kuwari +7
We investigate a magnetic dipolar system influenced by the -component of Zeeman splitting, Dzyaloshinsky--Moriya (DM) interaction, and Kaplan--Shekhtman--Entin-Wohlman--Aharony…
Tripartite measurement uncertainty in Schwarzschild space-time
Hazhir Dolatkhah, Artur Czerwinski, Asad Ali +2
The effect of Hawking radiation on tripartite measurement uncertainty in a Schwarzschild black hole background is analyzed in this study. Two scenarios are examined. In the first,…
Ergotropy and capacity optimization in Heisenberg spin-chain quantum batteries
Asad Ali, Saif Al-Kuwari, M. I. Hussain +5
This study examines the performance of finite spin quantum batteries (QBs) using Heisenberg spin models with Dzyaloshinsky-Moriya (DM) and Kaplan--Shekhtman--Entin-Wohlman--Aharony…
Physically Accessible and Inaccessible Quantum Correlations of Dirac Fields in Schwarzschild Spacetime
Samira Elghaayda, Asad Ali, Saif Al-Kuwari +1
In this study, we investigate the influence of Hawking decoherence on the quantum correlations of Dirac fields between \textit{Alice} and \textit{Bob}. Initially, they share a \tex…
A Study on Thermal Quantum Resources and Probabilistic Teleportation in Spin-1/2 Heisenberg XYZ+DM+KSEA Model under Variable Zeeman Splitting
Asad Ali, Saif Al-Kuwari, M. T. Rahim +3
We investigate the behavior of various measures of quantum coherence and quantum correlation in the spin-1/2 Heisenberg XYZ model with added Dzyaloshinsky-Moriya (DM) and Kaplan--S…
Trade-off relations of quantum resource theory in Heisenberg models
Asad Ali, Saif Al-Kuwari, Saeed Haddadi
Studying the relations between entanglement and coherence is essential in many quantum information applications. For this, we consider the concurrence, intrinsic concurrence and fi…
Quantum Characteristics Near Event Horizons
Asad Ali, Saif Al-Kuwari, Mehedad Ghominejad +3
We investigate quantum characteristics around Schwarzschild black hole, exploring various quantum resources and their interplay in curved space-time. Our analysis reveals intriguin…
