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…
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,…
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…
Jahn-Teller Effect for Controlling Quantum Correlations in Hexanuclear Fe Magnets
Hamid Arian Zad, Michal Jaščur, Asad Ali +2
We investigate the low-temperature magnetic and quantum properties of hexanuclear Fe complexes under an external magnetic field. We primarily study the impact of competin…
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…
