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…
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…
Simulating the Quantum Rabi Model in Superconducting Qubits at Deep Strong Coupling
Noureddine Rochdi, Atta ur Rahman, Rachid Ahl Laamara +1
The Quantum Rabi model serves as a pivotal theoretical framework for elucidating the nuanced interplay between light and matter. Utilizing circuit quantum electrodynamics on a chip…
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…
