 Well, I think we just need to take the physics that we already have and apply it to this problem. So some people say, well, we do need new physics. Well, a lot of the physics that we use in quantum computing is using a thing called Hilbert spaces. That's a fancy word that says, I just have a bunch of dimensions. Well, a bunch of dimensions by themselves are great. They have certain properties that you need in the solution. But those high dimensional spaces just can't be a bunch of pickup sticks like they're just sitting there.
