Your actualy pretty much correct. It's impossible to make a perfect clone of an atom, as you would have to know it's momentum and position at the same time, it's called the no cloning theorem. However what you can do is move that state from one atom to another, effectively just transferring it.

Incidentally this solves the whole uploading problem, as a perfect copy of your brain would neccesarily destroy the original.

I love it how you say that like it's a surprise. I know I'm correct. I'm probably getting a lot of downvotes because I really don't likes kaku's unsubstantiated blabbering. And it shows.

While you're right about 1 atom. A brain is more than that. You can copy the entire brain. But anything in "active" memory would be destroyed. There are millions on quantum interactions ongoing at any one time. But then this is essentially the same problem. You have to choose: measure the state, or the interactions.
