I am hard pressed to understand how information (successful communication) has any bearing whatsoever on quantum entanglement. Maybe you can enlighten me?
***It is basically Quantum Entanglement which generated the paradox because experiments show you can change the spin on one side and the entangled-spin of that particle-system changes INSTANTly across great distances. What Einstein called “spooky action at a distance”. It is the State of the Spin that was communicated faster than the speed of light.
That was what generated the EPR paradox in the first place.

You are assuming that communication [successful transmission of information] between entangled particles [e.g., photons] is what facilitates the matching of their respective states of spin. Yet this is what seems doubtful to me. The theory holds that entangled particles could be separated by a distance as great as can be measured from one "side" of the universe to the other (i.e., by ~47 billion light years). Yet experiments show that the spin matching takes place instantaneously, regardless of separation distance. This would seem to suggest that velocity — superluminal or just plain ol' C — is irrelevant to quantum entanglement.
At least in theory. Indeed, that would be "spooky action at a distance." But it's hard to see what communication has to do with it.
Anyhoot, in what sense is it reasonable to say that photons "communicate?" I mean, we're talking about photons — light quanta — here....
If they actually do, then this phenomenon needs to be elucidated.
Call me a little skeptical. Just trying to think through the problem. And it makes my head hurt! LOLOL!
Thanks so much for writing, Kevmo!
