Its all made up computation to fit the problem exactly. No real progress has been made in decades.
"Similarly, quantum factorisation is performed using sleight-of-hand numbers that have been selected to make them very easy to factorise using a physics experiment and, by extension, a VIC-20, an abacus, and a dog." https://www.schneier.com/blog/archives/2025/07/cheating-on-q...
This is just not true. There has been tremendous progress in the field. Starting with google’s experiment in 2019 on showing quantum advantage - admittedly on a useless problem, but quantum advantage nevertheless, to fault tolerant encodings by the Harvard group to recent demonstrations of a road toward advantage in generative models by goggle, to name a few. It’s still far away from running Shor’s algorithm to factor relevant numbers and break RSA and the like, but even there dramatic progress is being made, see, e.g., https://scottaaronson.blog/?p=9665
