Orthogonality Edges in Strong-Coupling Quantum Work Statistics
Atta ur Rahman, Muhammad Noman, S. M. Zangi +1
Strong coupling to a reservoir can do more than shift, broaden, or dress the work peaks of a driven quantum system. When the reservoir is infrared singular, a sudden change of a lo…
Gravitational cat states as a resource for quantum information processing
Atta ur Rahman, Ao-Xiang Liu, Saeed Haddadi +1
We investigate how resourceful gravitational cat states are to preserve quantum correlations. In this regard, we explore the dynamics of gravitational cat states under different si…
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…
