I'm not exactly sure where people extract free will from quantum randomness, so there's a bunch of quantum random number generators (using some sort of voltage breakdown/shot noise thing, I suppose), and that somehow conspires to help you think and make decisions instead of just jittering things a bit like you would expect from random number generators?
