  • Algorithms to calculate the partition function of quantum systems on quantum hardware have been proposed, but extensions to compute classical thermal averages are still scarce.

    “While algorithms to calculate the partition function of quantum systems on quantum hardware have been proposed, [182] which is not surprising in view of the quantum simulates quantum principle introduced above, extensions of these schemes to compute classical thermal averages are still scarce.”

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.
