Quantum-to-classical correspondence in Krylov complexity
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
We study quantum-to-classical correspondence of the Krylov space for evolutions driven by unitary maps with a classical limit. This entails a proper definition of corresponding qua…
Determining the ensemble N-representability of Reduced Density Matrices
Ofelia B. Oña, Gustavo E. Massaccesi, Pablo Capuzzi +5
The N-representability problem for reduced density matrices remains a fundamental challenge in electronic structure theory. Following our previous work that employs a unitary-evolu…
Purcell Enhancement and Suppression in Laser Cooling of Yb:YLF Nanocrystals in a Fabry-Pérot Microcavity
Lucas Mendicino, Franco Mayo, Christian Schmiegelow +1
We investigate the improvement of anti-Stokes laser cooling of a Yb:YLF nanocrystal in a Fabry-Pérot microcavity via the Purcell effect. Our analysis accounts for both the e…
Ergotropic characterization of continuous variable entanglement
Beatriz Polo-Rodríguez, Federico Centrone, Gerardo Adesso +1
Continuous-variable quantum thermodynamics in the Gaussian regime provides a promising framework for investigating the energetic role of quantum correlations, particularly in optic…
Determining the N-representability of a reduced density matrix via unitary evolution and stochastic sampling
Gustavo. E. Massaccesi, Ofelia. B. Oña, Pablo Capuzzi +6
The N-representability problem consists in determining whether, for a given p-body matrix, there exists at least one N-body density matrix from which the p-body matrix can be obtai…
Energetic Analysis of Emerging Quantum Communication Protocols
Raja Yehia, Yoann Piétri, Carlos Pascual-García +2
With the rapid development and early industrialization of quantum technologies, it is of great interest to analyze their overall energy consumption before planning for their wide-s…
