Abstract

Abstract We have demonstrated a prototypical hybrid classical and quantum computational workflow for the quantification of protein–ligand interactions. The workflow combines the density matrix embedding theory (DMET) embedding procedure with the variational quantum eigensolver (VQE) approach for finding molecular electronic ground states. A series of ‐secretase (BACE1) inhibitors is rank‐ordered using binding energy differences calculated on the latest superconducting transmon (IBM) and trapped‐ion (Quantinuum) noisy intermediate scale quantum (NISQ) devices. This is the first application of real quantum computers to the calculation of protein‐ligand binding energies. The results shed light on hardware and software requirements which would enable the application of NISQ algorithms in drug design.

  • Quantum computing can contribute to biochemical systems, biology, biochemistry, computation of protein-ligand interplay, mRNA codon optimization, and protein folding with higher-order speeds compared with conventional computers.

    “its contribution is possible in biochemical systems [7], biology [8], biochemistry [9], computation of protein-ligand interplay [10], mRNA codon optimization [11], and protein folding [12] to name a few with higherorder speeds compared with conventional computers.”

    From Quantum Computing in the Next-Generation Computational Biology Landscape: From Protein Folding to Molecular Dynamics (2024) · cites this paper as [10]

    The Abstract (p. 1) describes a quantum–classical workflow that calculates protein–ligand binding energies, supporting the part attached to citation [10]. The paper does not establish higher computational speeds than conventional computers; the Discussion (p. 10) instead describes current hardware limitations, including relatively high gate times. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • VQE-based methods have delivered data for parametrizing classical force fields.

    “This idea has been recently explored in Refs.[190] and [191], where VQE-based methods delivered data for parametrizing classical force fields.”

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.
