The complexity of industrial logistics and manufacturing processes increases constantly. As a key enabling technology of the upcoming decades, quantum computing is expected to play a crucial role in solving arising combinatorial optimization problems superior to traditional approaches. This study analyzes the current progress of quantum optimization applications in the logistics sector and aims to transfer an existing vehicle routing use case to a newly conceptualized matrix production use case regarding resource-efficient material flows. The simulation of the originating simple model is executed on a local circuit-based quantum simulator that emulates the behavior of real quantum hardware. Using a QAOA algorithm for problem-solving, optimal results have been achieved for all simulated scenarios.

Quantum computing presents a transformative opportunity for optimizing supply chain and logistics operations by addressing complex combinatorial challenges beyond the capabilities of classical computing. Traditional supply chain optimization relies on heuristic and mathematical models, which struggle with large-scale problems such as vehicle routing, warehouse management, demand forecasting, and last-mile delivery. Quantum computing, leveraging qubits and principles like superposition and entanglement, enables exponential computational power and efficiency. This paper explores quantum computing's applications in logistics, including quantum annealing for route optimization, fleet management, and supply chain network design.
