Better to cite the peer-reviewed final published version of a paper than the arxiv one, though I get that you did that because arxiv is free to access: http://www.nature.com/nature/journal/v526/n7575/abs/nature15759.html
But the point is, the violation of the Bell inequality does not imply FTL communication! COMMUNICATION! Something might have gotten there FTL, but you can't know without interrogating it with sub-FTL methods. And you almost certainly never will be able to, either.
As for my fundamental rule being 'classical physics': That is just not true. Classical physics has nothing to say about FTL travel. Quantum physics is an incomplete description of the universe, the incompleteness of which leads to these kinds of wrong conclusions. We know this and have done for ages; unifying quantum physics and relativity is one of the biggest challenges in theoretical physics. Observing violation of the Bell inequality is a demonstration of this, not that FTL communication is possible.
Entanglement has been known about for ages and we're getting to the point of using it for security, because you can't tamper with one end without it being evident at the other. But, while that part happens FTL, it is simply not the case that you choose the spin of one electron and its entangled friend over the road has the other spin. You don't get to choose, is the point. If you do spin filter the electrons, you break any entanglement. Random initial spin is part of entanglement. So you send a list of the measured spins along with your message, and the guy at the other end checks that his spins were opposite, and if so he knows the message is secure. But you SENT THE INFORMATION using sub-FTL methods, because there simply isn't any other way.
Pretty much every paper on arxiv (and I only say pretty much because I haven't checked every last one of them, but I have yet to read a single paper on there that wasn't published) was published in a peer reviewed journal. I found the copy in nature you linked first and then used it to find the arxiv copy. I've been providing peer reviewed articles from the very beginning, thanks.
You can know without sub-FTL communication. We know what the properties of a photon are. We know what the opposites, polarities and qualities of charm, spin, charge, etc.... are. You know when investigating the first particle to deduce state A also confers the information that the state of the other particle is B. You don't need to double-check that.
If I am looking North, I don't need to turn around and gauge the position of the sun to find South before inferring from the evidence that North is directly ahead of me that likewise South is directly behind me. East and West will also explicitly be where they have always been.
I can do this because the nature and properties of the magnetic poles and cardinal directions has been proven emphatically before my experiment. Likewise, the properties of quantum spin have been proven emphatically beforehand.
It's not a mystery. There is no guessing. Your entire position is based upon the false assumption that somewhere along the line someone has to make a guess. The only people who're guessing are the people who continue to insist that false Bell tests are somehow flawed through random, unidentifiable conditions.
I am on one side of the continent. My friend is on the other side. He is tapping out morse code that I am receiving over an electric line.
When I receive a message from him, I don't need to send a letter to him via stagecoach to confirm that the message he sent me in morse code was indeed sent in morse code. That part was agreed to before the message was ever sent, not after.
The fallacy that sub-FTL communication is required to confirm the information sent only applies to encrypted messages whose nature was not understood by both parties on transmittal. When a unifying language of communication is introduced all of that is immediately thrown out the window.
