This is yet another attempt to posit NISQ results (Noisy Intermediate Scale Quantum) as demonstrations of quantum supremacy. This does not allow us to do useful computational work; it's just making the claim that a bathtub full of water can do fluid dynamic simulations faster than a computer with a bathtub-full-of-water-number-of-cores can do the same computation.

If history is any guide we'll soon see that there are problems with the fidelity (the system they use to verify that the results are "correct") or problems with the difficulty of the underlying problem, as happened with Google's previous attempt to demonstrate quantum supremacy [1].
