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…

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…
