And I kind of decided that although academia was great, it would be hard to...

get the team together and keep them together for a long time to build this complicated machine.

And Google have the money, okay?

Yeah.

So we went there and we started off fairly small, mostly from people coming from my UCSB group.

And then in 2019, we published this quantum supremacy experiment with 53 qubits.

where we made a lot of qubits and we made them really good and, you know, fast and whatever, so that we could run some algorithm, a mathematical algorithm that, um,

produced some output that took much, much longer on a classical computer to emulate than do that.

It was not practical, but it was a demonstration of the power of a quantum computer.

That it worked.

So very simply, we have a metal wire and a metal wire that gets put together on this Josephson junction, which represents an inductor flowing through here.

And then from this wire to this wire, we have a capacitor here.

And then we set that up to oscillate at about five gigahertz cell phone frequencies, you know, to form the qubit.

Okay, this oscillating thing.

And then there's at low temperatures, superconductors, you know, all this magic, we can get quantum mechanical behavior out of that.

That's right.

What you can do is you put on microwave pulses to change the state of the quantum computer, change the way it oscillates.

And then we connect it to, it's a complicated readout circuitry to, you know, in the end, figure out what state it's in.

Okay.

And then you connect it.
