A resource-estimation framework places CVRP instances on a go/no-go decision diagram and shows that a higher-order encoding needs far fewer qubits than standard QUBO for early-advantage benchmarks such as Golden-5.

QADR decomposes n-qubit VQCs into local sub-circuits to reduce memory from O(2^n) to O(n * 2^{2d+1}) and mitigate barren plateaus, scaling to 2000 features on MNIST and wind turbine diagnostics while matching classical models.
Exascale classical simulation validates noise-tolerant performance of a 98-qubit QPU up to 48 qubits for LR-QAOA, with statistical analysis showing coherent regime up to 93 qubits before outputs become indistinguishable from random.
QAOA with default parameters is compared per-shot to Goemans-Williamson on realistic Max-Cut instances, highlighting practical limitations under black-box use.
Absence of quantum advantage for log-depth QAOA on the binary paint shop problem implies a classical mean-field algorithm achieving a paint-swap ratio of approximately 0.2799, outperforming known heuristics and quantum methods.

No quantum advantage implies improved bounds and classical algorithms for the binary paint shop problem
Absence of quantum advantage for log-depth QAOA on the binary paint shop problem implies a classical mean-field algorithm achieving a paint-swap ratio of approximately 0.2799, outperforming known heuristics and quantum methods.
