Decades after researches first sequenced the human genome, scientists throughout the world are still working to understand it. Despite diligent global efforts to link uncommon variations in DNA sequences with human disease, progress has been slow, in large part due to limitations in scientific understanding and in part due to limitations in computational technologies.Artificial intelligence has the potential to help scientists decipher the millions of genetic variations present in the genomes of different people in order to identify which ones lead to disease and which ones do not. In order to fully exploit the power of AI, however, scientists need to compare the genomes of thousands or tens of thousands of people. This task not only requires intense computational effort, it is also prone to error and will take years to complete.Quantum computing has the potential to facilitate that process. We are researchers with a long-standing interest in finding ways to use genetics in the clinic and developing new technologies to study the human genome. Combining quantum computing with AI has the potential to accelerate genomic analysis far beyond traditional methods. For time-sensitive medical conditions, faster decoding of genetic information can directly inform urgent treatment decisions and, in some cases, be lifesaving.Conventional vs. quantum computingIn conventional computing, individual bits of information – binary digits, also called bits – can represent only two states: namely, 0 and 1.AdvertisementAdvertisementHowever, the qubits used in quantum computing can have more than two distinct states. Adding qubits together increases the number of states exponentially. The power of quantum computers lies in being able to check all the possibilities at once for problems with large numbers of variables, rather than one at a time like even the fastest possible classical computer must do. This allows quantum computers to solve certain types of problems, such as factoring large numbers for today’s encryption schemes and performing combinatorial optimization to find the best route through a large number of points.[embedded content]Still, quantum computing is current …
