i think the cult ha resulted to communicating w quantum communication. Snowdn leaks showed that UK and Sweden were already doing it. I used to research it all more a few years back but the thing to do then was super heat diamonds w lasers, split them, then supercool them to a specific negative degree point. From that point on anything that you do to one will happen to the other anywhere. The transmission rate has been the issue in more recent articles but it could all be for public consumption and is likely far more advanced and working fine.
true too
