“13,000× faster” sounds huge, but I wonder what it’s being compared to. Quantum speedups are always tricky to measure

The article states: “...13,000 times faster on Willow than the best classical algorithm on one of the world’s fastest supercomputers...”

I agree it's not very precise without knowing which of the world's fastest supercomputers they're talking about, but there was no need to leave out this tidbit.

The paper talks only about the Frontier supercomputer which is #2 on Top500. But I think it was an analysis rather than them actually running it.

I was being sarcastic because 13,000 times faster is 4 orders of magnitude faster so it doesn't matter to which supercomputer it is compared.

I don’t understand how these papers get accepted

The field is nascent. The bar is not static.
