The project used a Deutsche Bahn dataset covering 190 trips across five German cities with ~98,500 possible scheduling cycles. The Quantum Approximate Optimization Algorithm (QAOA) was used to solve smaller subproblems within a classical framework managing the full-scale problem. Key findings: the approach produces feasible solutions on current hardware, solution quality improves as quantum processors scale, and the full pipeline ran end-to-end on an IQM quantum computer. The architecture is designed to generalize to logistics, energy, and manufacturing optimization challenges. ## Full article daily.dev links to this article rather than hosting it.
