Hybrid Lindblad dynamics and Bayesian inference from stochastic processes
Hilbert J. Kappen, Hilbert Kappen
We develop a Bayesian formulation of diffusive quantum-classical dynamics by treating the wave function and classical variables as components of an ordinary stochastic process. The…
Contracting Tensor Networks with Generalized Belief Propagation
Joseph Tindall, Grace M. Sommers, Hilbert Kappen
Recent years have seen a growing interest in the use of belief propagation - an algorithm originally introduced for performing statistical inference on graphical models - for appro…
Path Integral Quantum Control for Quantum Chemistry Applications
Peyman Najafi, Aarón Villanueva, Hilbert Kappen
The Path integral Quantum Control (PiQC) algorithm was recently introduced by Villanueva et al. (2025) as a new approach for computing optimal controls in open and closed quantum s…
Fröhlich versus Bose-Einstein Condensation in Pumped Bosonic Systems
Wenhao Xu, Andrey A. Bagrov, Farhan T. Chowdhury +4
Magnon-condensation, which emerges in pumped bosonic systems at room temperature, continues to garner great interest for its long-lived coherence. While traditionally formulated in…
Path integral control of open quantum systems
Aarón Villanueva, Hilbert Kappen
We investigate open-loop quantum state preparation for a class of open quantum systems whose dynamics follow a Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) master equation that adm…
Stochastic syncing in sinusoidally driven atomic orbital memory
Werner M. J. van Weerdenburg, Hermann Osterhage, Ruben Christianen +4
Stochastically fluctuating multi-well systems as physical implementations of energy-based machine learning models promise a route towards neuromorphic hardware. Understanding the r…
