Ooooooh, I’ve always wanted a monorail!

This paper released last summer makes the argument that quantum computing is in a similar state, and that any of the claimed numbers that were factored by quantum computing above 21 have basically been bullshit. I was listening to Security Now episode 1034 recently and they discussed the paper in reasonably understandable terms, but basically it boils down to factoring big numbers by picking numbers that are disallowed by modern algorithms because they’re binary weak primes.
