The Geometry of Transport in Quantum Walks and Parrondo's Paradox
Jose Alfredo de Leon, Mariana Pérez-Muralles, Jan Neuser +1
We study Parrondo's paradox -- the phenomenon where combining losing strategies yields a winning one -- in a minimal discrete-time quantum walk. We introduce the transport vector,…
Integrable, Mixed, and Chaotic Dynamics in a Single All-to-All Ising Spin Model
David Amaro-Alcalá, Carlos Pineda
We demonstrate that the Ising all-to-all (ATA) model exhibits a range of dynamics, from integrable to chaotic, including mixed behaviour across symmetry blocks within a single syst…
Exploring quantum ergodicity of unitary evolution through the Krylov approach
Gastón F. Scialchi, Augusto J. Roncaglia, Carlos Pineda +1
In recent years, there has been growing interest in characterizing the complexity of quantum evolutions of interacting many-body systems. When a time-independent Hamiltonian govern…
Weyl channels for multipartite systems
Tomas Basile, Jose Alfredo de Leon, Alejandro Fonseca +2
Quantum channels, a subset of quantum maps, describe the unitary and non-unitary evolution of quantum systems. We study a generalization of the concept of Pauli maps to the case of…
