Deutsche Bahn could expand the hybrid quantum scheduling approach to a larger subset of its network, moving from proof-of-concept to a limited operational pilot, provided IQM's hardware scales to handle larger problem instances within the next two years.
The successful proof-of-concept shows that the hybrid algorithm can handle the problem structure. Scaling to larger, operationally meaningful instances requires incremental improvements in qubit count and coherence, which are on IQM's roadmap; if achieved, a pilot deployment is feasible.
