Yilei Chen eprint paper that claims to "show a polynomial time quantum algorithm for solving the learning with errors problem (LWE) with certain polynomial modulus-noise ratios":

🍿eprint.iacr.org/2024/555 Yilei Chen is legit and has been publishing papers about this recently:

RSA factoring recap since shady people are making dumb claims right now.

Caveat: They used to use decimal digits for RSA key lengths, so "RSA-100" was 330 bits.
