Abstract

Quantum computers can in principle solve certain problems exponentially more quickly than their classical counterparts. We have not yet reached the advent of useful quantum computation, but when we do, it will affect nearly all scientific disciplines. In this review, we examine how current quantum algorithms could revolutionize computational biology and bioinformatics. There are potential benefits across the entire field, from the ability to process vast amounts of information and run machine learning algorithms far more efficiently, to algorithms for quantum simulation that are poised to improve computational calculations in drug discovery, to quantum algorithms for optimization that may advance fields from protein structure prediction to network analysis. However, these exciting prospects are susceptible to “hype,” and it is also important to recognize the caveats and challenges in this new technology. Our aim is to introduce the promise and limitations of emerging quantum computing technologies in the areas of computational molecular biology and bioinformatics.

TL;DR

This review surveys how quantum algorithms could affect computational molecular biology, especially statistical/machine learning, quantum simulation of electronic structure, and optimization. It argues that quantum simulation is likely the first useful application, while machine learning and optimization face serious input/output, hardware, and algorithmic caveats.

Key findings

  • Quantum machine learning could offer complexity advantages—e.g., HHL solves certain linear systems in \(O(\log N)\) versus \(O(N^3)\) classical matrix inversion—but extracting full solutions can require \(O(2^N)\) measurements, and most algorithms assume an unavailable QRAM.
  • A human genome (3 billion base pairs, \(1.2 \times 10^{10}\) classical bits, ~1.5 GB) could in principle be stored in ~34 qubits; 68 qubits would suffice for the genomes of every living human, though the state must be efficiently prepared.
  • Quantum simulation may solve the fully correlated electronic structure problem exactly within a basis set; a minimal-basis FCI calculation on the FeMo cofactor was estimated to require several months and circa 200 million high-quality qubits, though algorithmic advances lowered time requirements by orders of magnitude within 3 years.
  • Protein lattice folding is NP-hard, and the paper states quantum computers are not expected to give exponential speedup for NP-complete or harder problems; experimental work used D-Wave 2000Q for chignolin (10 residues) and Trp-Cage (8 residues), with evidence for only “limited quantum speedup.”

Methods

  • Narrative review, not a primary study; it introduces quantum information processing and then surveys three areas: statistical methods/machine learning, efficient simulation of quantum systems, and optimization problems.
  • Synthesizes published quantum algorithms, complexity comparisons, hardware error-rate reports, and protein-folding/optimization examples; no new dataset or experimental sample is analyzed.
  • The paper explicitly notes it leaves aside topics such as string algorithms for sequence analysis, medical imaging algorithms, numerical algorithms for differential equations, and biological network analysis.

Limitations

  • The authors state that space limitations forced them to omit several relevant areas, including sequence analysis, medical imaging, differential equations, and network analysis.
  • The authors emphasize practical caveats: input preparation and QRAM are unsolved, output extraction can erase speedups, appropriate data may be scarce, and fault-tolerant hardware requires large qubit overheads—e.g., surface-code error correction at 0.1% error could require several million qubits for 2,000-bit factorization versus ~4,000 noiseless qubits.
  • Evident from the text: as a non-systematic review, it does not define formal search or inclusion criteria, and many performance estimates are theoretical or prospective and may change with hardware and algorithmic advances.

  • Quantum entanglement is essential to perform quantum computing.

    “It is well established that this interconnection among several qubits, termed 'quantum entanglement,' is essential to perform quantum computing.”

    From Quantum Computing in the Next-Generation Computational Biology Landscape: From Protein Folding to Molecular Dynamics (2024) · cites this paper as [17]

    Section 2.1.1 calls entanglement fundamental for *useful* quantum computation. It says algorithms without entanglement can be enacted on a classical computer with no significant speed difference; that supports its importance for quantum advantage, but not the unqualified claim that it is essential to perform quantum computing at all. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • In recent years, the possibility of using quantum instead of or in combination with classical computing to solve biocomputing problems has emerged.

    “Interestingly, in recent years the possibility of using quantum instead of or in combination with classical computing to solve biocomputing problems has emerged [46, 47].”

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

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.
