They didn’t solve any kind of CS problem. As far as I can tell the problem they solved is “what is this complicated quantum system going to do” by building the complicated quantum system and seeing what it did. Then they claim it would take a gazillion years to simulate on a conventional computer. Which I’m sure is true.
