IQM and Deutsche Bahn Execute Hybrid Quantum Algorithm for Railway Scheduling

Superconducting quantum computer developer IQM Quantum Computers (Nasdaq: IQMX) and European rail operator Deutsche Bahn have published joint research demonstrating the execution of a hybrid quantum-classical optimization algorithm on real-world operational railway data. Executed end-to-end on IQM’s Emerald quantum processor, the study addresses the complex challenge of rolling stock planning—assigning physical train units to scheduled trips while minimizing operational costs and adhering to strict maintenance constraints.
