The key word being 'if' - cited research from the FT article that disclaims this: https://arxiv.org/pdf/2208.02199.pdf I have no expertise in QC/chemistry so I can't make a judgement other than to say it doesn't seem universally agreed that QC will be a silver bullet here.

One point of interest was the paper on quantum computing applied to quantum chemistry[1]. In that paper, they did not find generic exponential speedup for a list of chemistry problems with current quantum algorithms. There are 3 problems with this: a speedup does not need to be exponential in order to be incredibly valuable; a speedup does not need to be extremely generic, just enough to cover real-world use cases; and quantum algorithms are still in their infancy, and it's unclear how much more we might discover in the next 10-20 years. Furthermore, the paper itself links to a github…
