And when you get to those kinds of scale, the challenges become different.
Yeah, my name's Geoff Pride.
I'm the Chief Technical Director for SciQuantum in Australia.
It's one thing to build a machine that has tens or hundreds or thousands of qubits, but to go to a voter a million qubits, the challenges become different.
Companies that are building smaller machines are hoping that even though we can't implement full error correction on that scale, that something useful can be done.
But the trouble is, is that at the moment, we don't really think there are any useful applications that we can point to today and say, this is a lot better than what you could do on a conventional computer.
Controlling the world at the quantum level is a tricky thing.
And that's why it's natural that people ask about, well, how can we have, you know, 10 qubits and then 100 and then 1,000?
Because controlling the quantum world is a big job.
Avoid any such thing.
Can we go off the record for a second?
Yeah, so the first item here on the left, a silicon chip, 300 millimeters in diameter, consists of the photon sources and detectors and all the things in between that allow us to control our qubits.
I describe it as like a CD because when we stand here and look at it, we can see rainbow-like reflections coming off it.
And that's because there's all these millionth of a meter scale devices that are on there.
And just like on a CD grooves, they kind of give you that diffraction pattern, that rainbow effect that you see.
So it's quite a beautiful thing
to look at.
So we chop it up into smaller pieces and those pieces are themselves the chips.
We might not solve every problem known to humanity, but it can address probably a much, much wider scope than we think today.
Yeah, I hope so.
