The linked paper, [“Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog”](https://eprint.iacr.org/2025/1237.pdf) is also a great breakdown of how much the quantum factoring is more of a parlor trick and not practical for factoring RSA Keys, mainly since the prime factors are only a few bits off of each other and from the square root of the number being factored.
