Abstract

Abstract: This paper explores the application of quantum annealing to constraint satisfaction problems within complex simulations, specifically molecular dynamics. We introduce a novel quantum-driven constraint satisfaction algorithm designed to accelerate simulations by dynamically adjusting constraints during the annealing process. The core mechanism leverages quantum annealing to efficiently explore the solution space, offering a potential paradigm shift for computationally intensive simulations. This research aims to address the limitations of classical constraint satisfaction methods in large-scale molecular dynamics simulations, ultimately improving accuracy and efficiency.
