Quantum computers do defeat hidden-variable models, which would have to hide the computation somewhere. But yeah, Bell and EPR ruled those out years ago anyway.

- Strilanc 2y agoI don't see people who believe hidden variable models, like pilot wave, claiming quantum computers won't work. So I don't think quantum computers disprove hidden variable models. I do agree quantum computers disprove local hidden variable models. Because they can run Bell tests, and local hidden variable models can't violate the Bell inequalities.
- adastra22 2y agoLast time I checked pilot wave theory was not developed enough to permit modeling of quantum computers, or at least no one had done the work yet to apply the theory to that use case. It is very undeveloped.

- Strilanc 2y agoI don't think anyone has managed to write down a super deterministic model that can violate bell inequalities and contain computers. The computer bit is key here because it's what let's me create ludicrously difficult to solve setups, like picking measurement bases using sha1 hashes of starlight.
