Thermodynamics of quantum information in noisy polarizers
Maxwell Aifer, Nathan Myers, Sebastian Deffner
Among the emerging technologies with prophesied quantum advantage, quantum communications has already led to fascinating demonstrations -- including quantum teleportation to and fr…
Boosting thermodynamic performance by bending space-time
Emily E. Ferketic, Sebastian Deffner
Black holes are arguably the most extreme regions of the universe. Yet, they are also utterly inaccessible to experimentation, and even just indirect observation poses significant…
Exchange fluctuation theorems for strongly interacting quantum pumps
Akira Sone, Diogo O. Soares-Pinto, Sebastian Deffner
We derive a general quantum exchange fluctuation theorem for multipartite systems with arbitrary coupling strengths by taking into account the informational contribution of the bac…
Branching States as The Emergent Structure of a Quantum Universe
Akram Touil, Fabio Anza, Sebastian Deffner +1
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insigh…
Nonlinear speed-ups in ultracold quantum gases
Sebastian Deffner
Quantum mechanics is an inherently linear theory. However, collective effects in many body quantum systems can give rise to effectively nonlinear dynamics. In the present work, we…
Shortcuts to thermodynamic quasistaticity
Artur Soriani, Eduardo Miranda, Sebastian Deffner +1
The operation of near-term quantum technologies requires the development of feasible, implementable, and robust strategies of controlling complex many body systems. To this end, a…
