The mathmatics shows that this will always be the case, regardless of separation between the two particles. It wasn't until fairly recently that experimentation has proven this correct. As I understand it (and I might be wrong, I'm not a physicist) the effect is achieved by radioactively creating an entangled pair of particles (in the case of the experiment in china, photons) and then moving one of the pair to another location. At that point the one location can modify the spin properties of its particle, while the other location monitors the spin properties of its particle. Because if entanglement, they are always the opposite of each other. Therefore, the recieving facility can interpret data from the sending facility in a 1/0.

Interesting... Well that explains how they get entangled, but how does each pair of particles 'know' what the other is doing? Some kind of wormhole link or something... meh, I'll just file it under 'magic' for now
This stuff is so cool, dunno if anyone here has read the Ender's Game series of books, but this is pretty much exactly the communication system they used in there.
