Cute! I actually like the one, referenced at the end of the paper that's linked in the post, where they use a physics experiment without the usual error correction to factor values: Just re-run the experiment as many time as needed, with the errors producing a new result each time, until you hit no the result you need. So you're using your "quantum computer" as a random number generator that eventually hits the correct result by chance.

I can factor 83% of integers by dividing by 2 or 3

Lmao. Good job, I was waiting for someone to attempt this.
