industrial digital twins

Industrial digital twins have matured from static models into live operational systems that can monitor status, detect anomalies, predict behavior, and prescribe future operations; in manufacturing, they are already used for machine health, scheduling, maintenance, and virtual commissioning. The next step is not to replace the digital twin. It is to add a quantum execution layer on top of it so that the twin can hand off the hardest subproblems—routing, scheduling, layout, BoM selection, and constrained optimization—to QAOA, VQE, or related hybrid methods.
