Are you sure you don't mean if you assume non locality? PBR tightens things up beyond Bell a bit with a requirement of wave function being real itself.
Also correct me if i'm wrong but I believe the assumption is not against entangled states but instead against entangled states via independent preparation.
- madhadron 14y agoNo, I meant locality. I was more thinking the Hardy article.
- Dn_Ab 14y agoBell's theorem states no local hidden theory can be consistent with quantum mechanics. Only non local ones are allowed. PBR says not only are local hidden theories banned, the wave function must be real. Unless you abandon realism of quantum states of course. I'm not sure I understand what you are trying to say.
