Key points
- It compares VQE, CVaR-VQE, several QAOA variants, PCE, and QRAO using the same real-hardware procedure for four NP-hard problems.
- On IBM Heron r1 and r2, it records transpiled circuit sizes, execution results, and gate-count-based fidelity estimates for 247 method-problem combinations.
- At intermediate Heron-r2 error rates, noise began to dominate execution around F_est≈0.1, corresponding to approximately 770 two-qubit gates.
- No method produced a feasible solution for QAP, and qubit-efficient methods also ran larger problems only within the fidelity budget.
- The conclusions concern the tested implementations and hardware; they do not prove asymptotic inferiority of the entire QAOA family or quantum advantage over classical methods.
