IQM and Deutsche Bahn Apply Quantum Computing to German Rail Operations... Real-World Testing of 98,500 Train Combinations

A scheduling test using quantum computing for German rail operations was conducted, combining high-performance computing and quantum processors to address industrial-scale optimization problems based on actual rail timetables. IQM Quantum Computers and Deutsche Bahn tested hybrid quantum scheduling on 190 rail routes between five German cities, analyzing 98,500 train combinations. Quantum processors were used for specific optimization tasks while classical systems managed overall scheduling, with results published in IQM's whitepaper. The trial demonstrated quantum computing's viability for real-world rail optimization even with current hardware, showing improved performance with larger data sets and potential for complex scheduling advancements.
