IQM's whitepaper on hybrid quantum optimization for railway scheduling, developed with Deutsche Bahn.
Using a real operational dataset from Deutsche Bahn, a schedule of 190 trips across five German cities translating into roughly 98,500 possible cycles, the two organizations developed and tested a hybrid quantum-classical algorithm designed for enterprise-scale optimization problems.
