Scientists Upload First Real Genome to Quantum Computer
Researchers from the Wellcome Sanger Institute have uploaded the genome of the hepatitis D virus (HDV) to a quantum computer for the first time. Using IBM’s 156-qubit Heron quantum processing unit, the team demonstrated that quantum hardware can process real-world genomic data, according to a statement from the research team.
Why was the hepatitis D virus used for this test?
The team chose HDV because it is clinically relevant and possesses a compact genome. It consists of roughly 1,700 nucleotides of circular RNA, which the researchers described as one of the smallest known animal virus genomes.
The virus causes severe blood-borne liver infections through contact with infected bodily fluids. Despite its small size, the RNA folds into intricate secondary structures and mutates rapidly, providing a balance of complexity and biomedical importance, the team said.
How does quantum computing differ from classical genomic analysis?
Genomes are naturally stored as sequences of letters—A, C, G, and T/U. Quantum computers, however, operate using quantum states called qubits. The Wellcome Sanger Institute scientists converted the HDV genome into a quantum-compatible format so algorithms could analyze genetic information rather than theoretical problems.
Sergii Strelchuk, an associate professor at the University of Oxford and leader of the research team, stated that classical computers and artificial intelligence (AI) systems can get “hopelessly stuck” when analyzing pangenomes. Pangenomes are data structures that capture all genetic variation across many individuals, strains, or populations of the same species.
Strelchuk described pangenome information as a “tangled maze.” Because quantum machines can represent and process many genetic patterns simultaneously, they may navigate this combinatorial complexity more efficiently than traditional computers.
What genomic capabilities were demonstrated?
As part of the Quantum for Bio (Q4Bio) challenge, the researchers demonstrated four specific capabilities on quantum hardware. These included data encoding to convert DNA sequences and sequence alignment to map DNA fragments into reference genomes.
The team also performed pangenome assembly, which builds genomes from the DNA data of multiple individuals. Additionally, they used phylogenetic tree construction to map the evolutionary relationships between organisms.
What happens next for quantum biology?
James McCafferty, chief information officer at the Wellcome Sanger Institute, stated that loading the HDV genome opens the door to solving biological problems that were previously impossible for classical computers.
The team suggested that faster genomic analysis could eventually let scientists rapidly track infectious diseases, pinpoint disease-causing mutations, and improve the understanding of rare genetic disorders. However, Strelchuk and his colleagues noted in their statement that practical applications may still be years away.
A possible next step involves packaging these capabilities into a usable service. This would allow the broader scientific community to upload data and choose between classical or quantum approaches to solve computational challenges.
