From Local Nonclassicality to Entanglement: A Convexity Law for Single-Excitation Dynamics
Atta ur Rahman, Ao-xiang Liu, M. Y. Abd-Rabbou +1
We prove a simple dynamical law for excitation-preserving interactions: the {sum of local Wigner negativities} is upper-bounded by a fixed budget set by the initially excited state…
The Quantum Control Hierarchy: When Physics-Informed Design Meets Machine Learning
Atta ur Rahman, M. Y. Abd-Rabbou, Cong-feng Qiao
We address a wide spectrum of quantum control strategies, including various open-loop protocols and advanced adaptive methods. These methodologies apply to few-qubit scenarios and…
The Limits of Quantum Information Scrambling
Ahmed Zahia, M. Y. Abd-Rabbou, Atta ur Rahman +1
Quantum Information scrambling (QI-scrambling) is a pivotal area of inquiry within the study of quantum many-body systems. This research derives mathematical upper and lower bounds…
Detecting Entanglement in High-Spin Quantum Systems via a Stacking Ensemble of Machine Learning Models
M. Y. Abd-Rabbou, Amr M. Abdallah, Ahmed A. Zahia +2
Reliable detection and quantification of quantum entanglement, particularly in high-spin or many-body systems, present significant computational challenges for traditional methods.…
Quantum obesity and steering ellipsoids for fermionic fields in dilaton black hole
Samira Elghaayda, M. Y. Abd-Rabbou, Mostafa Mansour
This paper investigates quantum obesity (QO), quantum discord (QD), and the quantum steering ellipsoid (QSE) for bipartite Gisin states subjected to Garfinkle-Horowitz-Strominger (…
Non-Markovian Protection and Thermal Fragility of Quantum Resources in a Spin-1/2 Ising-Heisenberg Diamond Chain
Fadwa Benabdallah, M. Y. Abd-Rabbou, Mohammed Daoud
This research investigates the dynamics of entanglement and uncertainty-induced nonlocality in a spin-1/2 Ising-Heisenberg diamond chain subjected to local non-Markovian decoherenc…
