Real-world optimization on emerging quantum/Ising platforms

Determine whether emerging specialized hardware platforms for combinatorial optimization, including Ising machines and quantum annealers, can effectively solve real-world optimization problems given current technological limitations.

Background

The paper models a multi-objective supply chain logistics problem as a QUBO and proposes hybrid quantum-classical solvers executed on current trapped-ion quantum hardware and classical/quantum-inspired methods. While specialized non-classical platforms are promising for combinatorial optimization, their practical utility on industrial-scale instances remains uncertain due to hardware constraints.

The authors explicitly note that translating real-world problems to such platforms is challenging at present, motivating their hybrid approach and experiments; they highlight that establishing practical effectiveness of these platforms for real-world optimization is a considerable open problem.
