Device-Independent Quantum Key Distribution: Protocols, Quantum Games, and Security
Syed M. Arslan, Saif Al-Kuwari, M. T. Rahim +1
Quantum Key Distribution (QKD) is based on the laws of quantum mechanics to enable provably secure communication. Despite its theoretical security promise, practical QKD systems ar…
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…
