The abstract mentions Deutsch November 1991, just a bit too late for Harry. Deutsch is specificaly about quantum mechanics and that the result is computable. He suggests that you could solve hard problems with a CTC, but I don’t think he pursues it. I am amused by the caption to figure 5: “Network for finding a fixed point of f?”
