Quantum thermometric sensing: Local vs. Remote approaches
Seyed Mohammad Hosseiny, Abolfazl Pourhashemi Khabisi, Jamileh Seyed-Yazdi +4
Quantum thermometry leveraging quantum sensors is investigated with an emphasis on fundamental precision bounds derived from quantum estimation theory. The proposed sensing platfor…
Single-photon emission modeling with statistical estimators for the exponential distribution
Artur Czerwinski, Katarzyna Czerwinska, Xiangji Cai +5
Single-photon sources are used in numerous quantum technologies, from sensing and imaging to communication, making the accurate modeling of their emissions essential. In this work,…
Controlled quantum secure remote sensing
Muhammad Talha Rahim, Saif Al-Kuwari, Mahmood Irtiza Hussain +1
Quantum resources enable secure quantum sensing (SQS) of remote systems, offering significant advantages in precision and security. However, decoherence in the quantum communicatio…
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…
