Optimal Dynamic Cooling of Multiple Qubits
Mattia Reda, Massimiliano Sacchi, Chiara Macchiavello +1
We solve the closed-system problem of cooling qubits, selected from identical thermal qubits, to the lowest common local temperature allowed by unitarity. The optimal proto…
Engineering Nonclassical States via the Dynamical Casimir Effect
Maristella Crotti, Luca Razzoli, Giacomo Guarnieri +3
Nonadiabatic driving in ultrastrongly coupled light--matter systems is commonly regarded as a source of errors, as counter-rotating interactions convert vacuum fluctuations into re…
Experimentally probing Landauer's principle in the quantum many-body regime
Stefan Aimet, Mohammadamin Tajik, Gabrielle Tournaire +6
Landauer's principle bridges information theory and thermodynamics by linking the entropy change of a system during a process to the average energy dissipated to its environment. A…
Stability of emergent time periodicity in a few-body interacting system
Steve Campbell, Jens Eisert, Giacomo Guarnieri
We examine the onset and resilience of emergent time periodicity in a few-body all-to-all interacting Lipkin-Meshkov-Glick model, where one of the constituents is locally in contac…
