Abstract

Abstract Molecular science is governed by the dynamics of electrons and atomic nuclei, and by their interactions with electromagnetic fields. A faithful physicochemical understanding of these processes is crucial for the design and synthesis of chemicals and materials of value for our society and economy. Although some problems in this field can be adequately addressed by classical mechanics, many demand an explicit quantum mechanical description. Such quantum problems require a representation of wave functions that grows exponentially with system size and therefore should naturally benefit from quantum computation on a number of logical qubits that scales only linearly with system size. In this perspective, we elaborate on the potential benefits of quantum computing in the molecular sciences, i.e., in molecular physics, chemistry, biochemistry, and materials science.

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

  • Quantum computers have been proposed to simulate quantum systems efficiently.

    “By exploiting their quantum mechanical properties, quantum computers have been proposed to simulate quantum systems efficiently [9–13].”

    From Drug design on quantum computers (2024) · cites this paper as [12]

  • Quantum phase estimation algorithms are likely to compete with and beat the best traditional approaches for strong electron correlation cases, such as metalloenzyme active sites and electronically excited states.

    “Detailed resource estimates [13,140] showed that algorithms based on quantum phase estimation are likely to compete and beat the best traditional approaches for cases of strong electron correlation as they occur in active sites of metalloenzymes (and in electronically excited states; see below).”

    From Quantum Computing for Molecular Biology** (2023) · cites this paper as [13]

  • As the molecule size increases, VQE requires a larger number of sub cycles for Hamiltonian averaging, projecting to unfeasibly long runtime for systems of practical importance.

    “as the molecule size increases, VQE requires a larger number of sub cycles for Hamiltonian averaging (because of more terms in the Hamiltonian), projecting to unfeasibly long runtime for systems of practical importance [90, 102, 106, 107]”

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.
