I have a basic question about the concept of non-locality in QM. I'll explain as I understand it (correct me if I'm missing the essence): The so called 'non-local' property of two entangled photons (for instance), suggests that the measurement of one of the pair 'communicates' with the other, possibly FTL. However, since in the case of photons that are space-like separated, in accordance with special relativity, cannot communicate FTL, there arises a paradox. However, is there even a causal relation between the two photons if they are space-like separated, and can we even speak of 'influences' (FTL or not)? Are we just seeing FTL because we are not equiped to see the nature of the correlation between the particles? I know this may appear too philosophical, apologies for that. I don't mean to. It is just that this problem makes more sense to me if I'm taking a informational approach (which I don't discuss here).
