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,…
Quantum vs Classical Erasure: Equal Bounds but Unequal Costs
Jan Neuser, Jake Xuereb, Pharnam Bakhshinezhad +1
Irreversibility has a fundamental thermodynamic cost, erasing information inevitably generates heat. This connection is quantified by the Landauer bound, which gives the minimum di…
Quantum Field Theory of Black Hole Perturbations with Backreaction VI. Apparent Horizons, Quasi-Local Mass and Effective Classical Metrics
Jonas Neuser, Thomas Thiemann
In a recent series of papers we developed a first-principle and gauge invariant approach to black hole perturbation theory valid to any order. We included back reaction effects to…
Prodiabatic Elimination: Higher Order Elimination of Fast Variables with Quantum Noise
Jan Neuser, Marcelo Janovitch, Matteo Brunelli +1
We introduce the prodiabatic elimination, a powerful approximation technique that systematically extends the adiabatic elimination of fast degrees of freedom in light-matter couple…
Quantum Field Theory of Black Hole Perturbations with Backreaction V. Beyond Second Order Perturbations
Jonas Neuser, Thomas Thiemann
Black hole perturbation theory beyond second order is not well understood because typically one defines the meaning of gauge invariance order by order which is ambiguous. In this s…
