B Information transfer using entanglement?

Click For Summary
The discussion centers on the feasibility of transferring information through quantum entanglement, specifically questioning whether changing the measurement angle of one particle (A) affects the outcomes of another particle (B). It is established that while measurements on entangled particles do not allow for faster-than-light information transfer, correlations between the measurements can be influenced by the angles chosen. The participants explore the implications of these correlations, suggesting that while individual outcomes appear random, the overall patterns may reveal information about their relationship. Ultimately, it is concluded that without additional information from both particles, one cannot determine if the outcomes are entangled, reinforcing that entanglement does not facilitate direct information transfer. The conversation highlights the complexity of interpreting quantum mechanics and the nuances of measurement dependencies in entangled systems.

@morrobay: thanks for your example in post #15 and the example in the paper. I am sorry, with all due respect, but I am not sure what you are saying here. Are you saying that the outcomes are interdependent, and that they are not dependent on the settings?

Then I would agree, with the caveat that the outcomes may depend on the settings. :smile:

I think that there is - in principle - not enough information to establish how the outcomes are created. The situation is symmetrical, so it could go either way. B depends on A and vice versa. However, that is my point: because there is not enough information in principle, that leaves room for the possibility that B (outcomes) depends on A (outcomes/settings). However, because the opposite is also possible, it seems difficult if not impossible to substantiate a claim of causality or even influence.

That said, I think the outcomes depend on the settings, because the correlation depends on the settings. So if one were to rule out 'an effect' (non-locality) one would have to stick with the outcomes depending on the local settings (like you seem to do?). One step further is to suggest that the outcomes might interdepend non-locally (of 'the other' settings), like I do. :smile:
