A Bayesian formulation of hybrid quantum-classical dynamics
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…
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…
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…
