Guerreschi and Matsuura raised scaling issues for QAOA.
“With such peculiarities in mind, one should also view the results of Guerreschi and Matsuura, who found the point of quantum supremacy for QAOA to be in the order of several hundred to thousand of qubits [56] and further raised scaling issues [60].”

The Introduction (p. 2) explicitly highlights challenges in scaling QAOA, and Hardware Performance (p. 4) reports that performance on some problem types worsens as problem size increases. But the cited paper presents these as its own findings; the passages do not establish that Guerreschi and Matsuura raised those issues. (LLM, conf=0.86)
Experimental — accuracy not yet measuredBy re-analyzing experimental data from Google's Sycamore quantum processor on QAOA for graph optimization, reachability deficits were discovered, with graph density replacing clause density as the order parameter.
“Moreover, by re-analyzing the experimental data from Google's Sycamore quantum processor on the application of QAOA to various graph optimization problems (Harrigan et al. , 2021), authors from (Akshay et al. , 2020b) also discovered reachability deficits in this case, where the graph density (defined as the ratio between the number of graph edges to the number of graph nodes) replaces the clause”

The optimal depth of QAOA as a tradeoff between ansatz accuracy and error rates has been found to be p=1 and p=3, respectively.
“Thus, as an example, the optimal depth as a tradeoff between ansatz accuracy and error rates has been found to be p=1 and p=3, respectively [5, 60].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
