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…
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…
Smooth, invariant orthonormal basis for singular potential Schroedinger operators
J. Neuser, T. Thiemann
In a recent contribution we showed that there exists a smooth, dense domain for singular potential Schrödinger operators on the real line which is invariant under taking derivative…
