So it's accessing the fact that actually there's an interpretation of quantum mechanics called the many worlds interpretation, where you're to imagine these, you know, infinite pretty much sea of universes. And the computer kind of goes and does the calculation in parallel and then brings them back together again at the end.

And I mentioned David Deutsch earlier, who's a fascinating writer in this field and the instigator of many of these algorithms. early on, who would say that. He would say, this is what is happening. There is no other explanation. How do you explain the fact that this quantum computer can do something that no classical computer can ever do? How do you explain it? Where is it doing the math?

Well, I don't fully understand that. I feel so much better.

It is a photograph of, in a real sense, that the photons are arriving and you're detecting them. So it's a photograph of... So that's what it actually looks like. If you think about what, I think what must be happening is you're getting these photons. It is true to say that, again, this many worlds interpretation of quantum mechanics would be that these entangled photons...

If you send them on a path, then they, going back to Feynman, if you calculate, the way you calculate how a photon goes from A to B or an electron, whatever it is, it just formally is you allow it to take all possible paths. That's one way of calculating the probability it will go from one place to another. And when you get entanglement, it gets more complicated.

But you're essentially, you are mathematically saying I allow it to go on all paths. And so really there you're seeing what an interference pattern is, is you're seeing the result of the fact that these particles can go on all loads of paths and interfere with each other and make a pattern you can see. And I think that's what that is.

It is beautiful, isn't it?
