So, "verifiable" here means "we ran it twice and got the same result"?

> Quantum verifiability means the result can be repeated on our quantum computer — or any other of the same caliber — to get the same answer, confirming the result.

It means that they transcended the "works on my machine" stage, and can reliably run a quantum algorithm on more than one different quantum computer.

They haven’t, though?

At least they claim that: «Quantum verifiability means the result can be repeated on our quantum computer — or any other of the same caliber — to get the same answer, confirming the result. This repeatable, beyond-classical computation is the basis for scalable verification.» (emph. mine)

But apparently they haven't demonstrated the actual portability between two different quantum computers.

What’s the difference between the claim that they’re making and what you say they haven’t done?
