It’s really hard to parse both the announcement (too much hyperbola) and the article (too technical), however as I understand it, this is what quantum computing should be good at. Not at making classical algorithms faster, but at simulating quantum physics experiments. This is a good direction and I find it more plausible than “we factored numbers faster”.
This SHOULD be the main application of the tech. It’s hard to tell if it is because authors can’t do science communication, they can apparently only do sales.
