Is an ansible in the works.
In the book Ender's Game Oeson Scott Card predicted the blogosphere at a time when few considered the internet like that. In his later books to make the plot work he needed FTL travel of information. The way he had it done was by splitting a philote and transporting the halves then a move on one would instantly cause the same movement on the other. This is clearly against physics, right, nothing can travel faster than light. Enter quantom in recent experiments photons were split. They were then placed far away so there could be no communication between them. At the time both photons had undetermined spins. In fact they could have been spinning in all the different directions and according to superposition were going in all possible directions. Then one photon half was measured instantly the other half recorded the same spin. Somehow the photons communicated instantly. The useful thing is that it theoretically works under any distance constraint including several light years.

I don't understand how it works, but they have absolutely proven you can't use quantum entanglement to carry information. So it's a neat trick, but useless.

Couldn't you use some form of morse code.

I think that you would be able to communicate using this method, but the exact way is beyond me. Is it possible that we have philotes that do the communicating/translating for us? I'm getting into philotics now, but it seems like a logical explanation. Sure, you yourself can't send information across it, but what if the photon in question can send a message to the other photon? And you can't disprove something if you don't understand it yourself.
