I believe the Aspect experiment and Bell's theorem taught us that that the disruption of entanglement is fundamentaly non-local, that even if there are hiddin variables, they too are non-local in nature.

Correct me if this belongs in a different thread. The question I would like to ask is does any string theory, with it's multidimensial ideas offer any insight concerning those kinds of hidden variables? Is the consideration of an extradimensional cause resulting in instant disentanglement a property of any of the well known string theories.

Swansot,

You were very helpful.

Thanks

I think I see, but to be sure -

[*]We can never actually observe a particle in a supperposition.

[*]Supperposition particles and particles which have committed to its state, (because their correlated partner has been measured) are indistinguishable when they enter our measurments.

Correct me.

Regarding "But it wouldn't do you any good for FTL communication anyway, because you don't know what state the particle would be in."

If you could tell if it were in a superposition beforehand, you would recieve information regarding the behavior of the opposite scientist, (wether they took a measurment or not).

I feel like I'm missing something. Thank you for your patience.

And I guess it's impossible to simply tell if the others wave function has collapsed, or not, without causing it to collapse. All observations would be of particles, not waves?

If you measure the entangled attribute, you destroy the entanglement — the wave function collapses.

Thank you,

If you're able to collapse the wave function of an entangled particle at a distance, what keeps us from being able to input a code into the process and communicate at a distance via a series of entangled particles shot from between. I know it's impossible, but I'd appreciate a clearer explaination then I've been able to find elsewhere.

What is the nature of the observations affect on the entanglment. Could there ever be a way to observe without interfering, or is it an absolute rule. If it's absolute, how was it determined. ie examples of experiments
