A Claimed Quantum Computing Breakthrough Was Just Debunked

New analysis shows that a widely-publicized quantum computing “breakthrough” doesn’t replicate under closer scrutiny.
Researchers attempted to reproduce the claimed quantum advantage and found conventional explanations for the results — suggesting the original announcement oversold what the device actually did.
research done a while back in march 2025 at the Zurich University of Applied Sciences.
Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a dog.

Conclusion:
In this paper we showed how to replicate current quantum factorisation records using first a VIC-20 8-bit home computer from 1981, then an abacus, and finally a dog. In terms of comparative demonstrated factorisation power, we rank a VIC-20 above an abacus, an abacus above a dog, and a dog above a quantum factorisation physics experiment. Finally, we provided standard evaluation criteria for future claimed quantum factorisations.
