I don't think many cryptography engineers take Gutmann's paper seriously.

From the paper:

> After our successful factorisation using a dog, we were delighted to learn that scientists have now discovered evidence of quantum entanglement in other species of mammals such as sheep [32]. This would open up an entirely new research field of mammal-based quantum factorisation. We hypothesise that the production of fully entangled sheep is easy, given how hard it can be to disentangle their coats in the first place. The logistics of assembling the tens of thousands of sheep necessary to factorise RSA-2048 numbers is left as an open problem.

The paper is a joke, but Gutmann does make some useful, non-joke suggestions in section 7. There's probably room for a serious, full-length paper on quantum factorization evaluation criteria.
