If we find quantum computers are no more powerful than classical ones, well then perhaps CTCs exist.

Although what if quantum computing is actually a result of CTC under the space time fabric? (Probably a nonsensical proposition eh?)
- jessriedel 8y agoIt's generally considered inelegant but not nonsensical. There exist hidden-variable theories that reproduce all the normal predictions of quantum mechanics (including quantum computations), but they require non-local interactions. I think a restricted set of CTCs could mediate those interactions.
