You can save time by first looking at the required noise performance of these schemes. From the abstract of the paper:

>On superconducting architectures with 10−3 physical error rates...

So good old 0.1% noise performance again. That seems to have come from the "20 million noisy qubits to break RSA" scheme[1] from back in 2019. That level of noise performance is still wildly out of reach and for all we know might be physically impossible.

It's only ~1 order of magnitude away from current capability. current gen QCs are around 1% gate error rate, and a decade ago SOTA was ~10% error rate, so if progress continues it should be achievable relatively soon.

		People don't understand the exponential function. Let's say you start adding water to a fish tank drop by drop, and double the number of drops each time. One drop, two, four, eight, and so on. When is the fish tank half full? When it's like 1/16 of the way full, or something like that.
