Quantum Mpemba Effect in a Four-Site Bose-Hubbard Model
Asad Ali, Hamid Arian Zad, Muhammad Irtiza Hussain +5
We investigate relaxation-order inversion, known as the quantum Mpemba effect (QME), in a minimal open many-body system called a one-dimensional four-site Bose--Hubbard chain gover…
Quantum Repeater Chains via Cavity Magnon for Scalable Quantum Networks
Mughees Ahmed Khan, Syed Shahmir, Muhammad Talha Rahim +2
Scalable quantum networks require quantum repeaters to overcome major challenges such as photon loss and decoherence in long-distance quantum communication. In this paper, we prese…
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…
Coherence, Transport, and Chaos in 1D Bose-Hubbard Model: Disorder vs. Stark Potential
Asad Ali, M. I. Hussain, Saif Al-Kuwari +6
Quantum coherence and phase transitions are studied in a finite one-dimensional Bose--Hubbard model using exact diagonalization under thermal fluctuations, a Stark potential, and d…
