You need to decide how can you encode a quantum entangled set of qubits in such a way that there is an algorithm for doing the equivalent of voting, right?

You know, picking the majority rule.

And so people have done that.

And then you need to build into your quantum computer algorithms.

um, steps in the algorithm that along the way, uh, massage the qubits to make sure that they have not been, uh, have not been subject to noise.

So you're going to have to build, it's going to be an important step if you want to build quantum computers that can do commercially useful applications.

I do, I do.

It's going to be trickier than we thought to build large quantum computers.

They're very, very fragile.

And so the theory is there, the technology for building qubits is there, but keeping them all decohered, et cetera, or coherent, I suppose I should say, is going to be tricky.

So, yeah.

Absolutely.

Yeah.

I mean, he was one of the people who invented the idea of quantum computing.

But, you know, now there's money involved.

So lots of people are very, very active in both the theory side and the technology side.

And so the people like David who are, you know, the big picture creative thinkers, they're thinking about other things these days.

Yes.

Yeah, and I think that these are fascinating questions.

Actually, that's a good segue.
