QAOA Applied to Graph Partitioning: Laying Foundations for Quantum Supply-Chain Routing

Toward the end of April 2014, theoretical researchers explored the Quantum Approximate Optimization Algorithm (QAOA) and applied it to graph partitioning problems—key subproblems in route planning, facility zoning, and load balancing. By mathematically modeling optimization instances as cut and partition problems, they showed how QAOA could approximate solutions more efficiently than classical heuristics under certain structures.

Though purely theoretical in this early phase, this research was seminal: it signaled how algorithms tailored for logistics problems—like grouping delivery zones or balancing freight across hubs—could be adapted into quantum frameworks as hardware matures. It began the bridge between algorithmic theory and real-world logistics operations.
