"'Willow,' the tech giant's new quantum chip, succeeded in solving a computational problem so complex it would have taken today's best super-computers an estimated 10 septillion years to solve it"

Thoughts? They claim there is a infinite mathematical space called the Hilbert space that they are accessing.

maybe i missed hte answer to this, but if the problems is essentially impossible to solve, how do they know the answer is correct? and it seems like a giant leap to say since they solved a problem really fast that that proves a multiverse
