Entangled particles communicate instantaneously through space. That is to say, communication faster than the speed of light. This was actually one of the reasons that Einstein did not want to accept quantum theory. In fact, he proposed quantum entanglement as an argument against the validity of quantum theory. According to quantum theory, transfer of information faster than the speed of light should be possible (via quantum entanglement). Therefore, quantum theory was incorrect/incomplete- that was Einstein's reasoning.
There would still have to be an entanglement step. The photons need to be coupled. This is currently accomplished by a laser across long distances. I suppose that in this sense there is a latency at the speed of light to add new particles. But once the photons have been entangled they can communicate instantaneously.
