Checking the required hardware noise performance:

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

So still 1-2 orders of magnitude better than what we can achieve.

This is against a 256 bit elliptic curve. For some reason most people are stating the difficulty of using Shor's against 2048 bit RSA. Elliptic curves are easier to break with Shor's. I wonder how much of the optimization came from that fact alone...
