As far as anyone can tell you can't use it transmit information. Their states are mirrored but you can't modify the state of on of the pairs to change the state of the other, that just breaks the entanglement. So all you really have are two particles that happen to be in the same random state at any given time.
I don't think you can even tell given only one of the particles in a pair if it is still entangled so you couldn't even destructively send small amounts of information either. It's a neat work around for semihard scifi but the universe is stubbornly resistant to any pathways for anything including information travelling faster than the speed of light.
