Entanglement certification in bulk nonlinear crystals for degenerate and non-degenerate SPDC: spectral filter effects on transverse spatial correlations
Hashir Kuniyil, Asad Ali, Saif Al-Kuwari
Spatial correlations of photon pairs from spontaneous parametric down-conversion (SPDC) underpin quantum imaging and entanglement certification. We present the first systematic stu…
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…
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,…
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…
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…
Optimizing Continuous-Wave-Pumped Entanglement-based QKD in Noisy Environments
Hashir Kuniyil, Saif Al-Kuwari, Asad Ali +2
Quantum key distribution (QKD) has emerged as a promising solution to protect current cryptographic systems against the threat of quantum computers. As QKD transitions from laborat…
