On-site interactions in quantum thermal machines: efficiency, rectification and entanglement beyond local and global master equations
Salvatore Araceli, Teddy H. M. Ong, Baptiste Debecker +4
Advances in experimental techniques have opened new routes for harnessing non-equilibrium dynamics in mesoscopic quantum systems. In this context, we study the impact of on-site in…
Phase-dependent role of dissipation across the Aubry-André-Harper transition
Gerardo Suárez, Baptiste Debecker, Francesco Cosco +4
We study transport across the Aubry-André-Harper localization transition in the presence of non-Markovian dissipation. For a single particle initially at the center of the chain,…
Symmetric Resourceful Steady States via Non-Markovian Dissipation
Baptiste Debecker, Eduardo Serrano-Ensástiga, Thierry Bastin +2
We prove a no-go theorem for symmetry-based dissipative engineering of collective-spin steady states: in spin-only Lindblad dynamics with jump operators linear in the collective-sp…
Solving Helmholtz problems with finite elements on a quantum annealer
Arnaud Rémi, François Damanet, Christophe Geuzaine
Solving Helmholtz problems using finite elements leads to the resolution of a linear system which is challenging to solve for classical computers. In this paper, we investigate how…
Variational quantum algorithm for solving Helmholtz problems with high order finite elements
Arnaud Rémi, François Damanet, Christophe Geuzaine
Discretizing Helmholtz problems via finite elements yields linear systems whose efficient solution remains a major challenge for classical computation. In this paper, we investigat…
Bound entanglement in symmetric random induced states
Jonathan Louvet, François Damanet, Thierry Bastin
Bound entanglement, a weak -- yet resourceful -- form of quantum entanglement, remains notoriously hard to detect and construct. We address this in this paper by leveraging symmetr…
