 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. No, they have to create structure. So one of the approaches that I did for my PhD 20 years ago already was,
