CCD-QAOA incorporates counterdiabatic terms into the QAOA ansatz and shows higher approximation ratios than standard XY-mixer, Grover-mixer, and penalty QAOA for portfolio problems with budget and risk constraints.
Adaptive CVaR sampling, two-stage optimization, and a heavy-hex-native deep-chain ansatz layout improve VQA results on dynamic portfolio optimization, with the new layout best on IBM hardware, though no quantum advantage over classical solvers is found.
Numerical benchmarks identify a minimum problem size where variational quantum circuits for Max-Cut outperform sampling on average, with quantified separation from greedy methods and instance-level performance correlations.
