Solving the quantum many-body problem with artificial neural networks

Abstract

Machine learning and quantum physics: Elucidating the behavior of quantum interacting systems of many particles remains one of the biggest challenges in physics. Traditional numerical methods often work well, but some of the most interesting problems leave them stumped. Carleo and Troyer harnessed the power of machine learning to develop a variational approach to the quantum many-body problem (see the Perspective by Hush). The method performed at least as well as state-of-the-art approaches, setting a benchmark for a prototypical two-dimensional problem. With further development, it may well prove a valuable piece in the quantum toolbox. Science , this issue p. 602 ; see also p. 580

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The matrix S is typically ill-conditioned and needs to be regularized.

    “In practice, the matrix S is typically ill-conditioned and needs to be regularized, for which there exist several approaches 47,56,121 .”

    From Beyond-classical computation in quantum simulation (2025) · cites this paper as [47]

    Appendix A (p. 8) says the covariance matrix S can be non-invertible and describes the authors’ preferred regularization. It does not say S is typically ill-conditioned or that regularization is necessary: it also gives a pseudo-inverse as an alternative. (LLM, conf=0.86)

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.
