Getting entangled particles to both sides of the conversation, maybe there's a way to entangle particles at a distance? I believe current attempts creates entangled photons at one end and sends half of entangled pairs to the other end. Remember that once you "read" from an entangled pair, it becomes "unentangled". Plus photons like to become unentangled along the way!
Literally can do the same thing with unentangled pairs with all the benefits (except one) with none of the downsides! The reason to do so (which is an awesome reason) is secure communication.
