I'm sorry to sound like the idiot here but, does this mean much lower latency, if so by how much? Furthermore, how does this make communication more secure? Ar

  No. Information doesn't travel faster than light, ever.

  Information never goes faster than light, even though quantum information does. But, the communication is more secure because the data which goes from node to node is quantum encoded. So if someone would eavesdrop, the code would break and the receiver would immediately know there was an eavesdropper, as he would no longer be able to decode the information. Quantum information can only have 1 sender and 1 receiver.

  It reduces the latency a little bit as you only have the distance between two points, rather than the longer path that it would take for a signal to travel in a cable. In addition the speed of light is on the order of 30% slower traveling through a fiber optic cable than through a vacuum. This probably will be where the biggest gain in latency will be.
