 Well, a lot of the physics that we use in quantum computing is using a thing called Hilbert spaces. Okay. So that's a fancy word that says, I just have a bunch of dimensions, right? 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.
