Quantum Optimisation Cuts Measurement Needs with New Bayesian Approach
Researchers Siran Zhang and Shuming Cheng at Tongji University introduced a resource‑efficient Quantum Approximate Optimisation Algorithm (QAOA) that targets the cut value of the most probable bitstring and incorporates Bayesian optimisation with adaptive shot allocation. Tested on 3‑regular MaxCut instances, the method matches conventional QAOA solution quality while cutting the required quantum measurement shots by up to 30%. The framework shifts focus from average‑value objectives to single‑solution quality, addressing the limited‑shot constraints of near‑term quantum hardware. Further work will explore scalability to larger combinatorial problems.
