Future comms: find a way to keep an entangled particle in a magnetic trap. its also entangled mate is in another magnetic trap. You can read its spin with a laser. If the laser is polarized, you can make it have one spin or the other depending upon which side of the trapped particle you illuminate with the laser pulse. This can be how you exchange ones and zeros, hence communicate. In theory nobody can eavesdrop on the changes in the entangled partices, although each side is still subject to normal bugging in the room etc.
A side benefit is that in theory there is no range limits or even signal delays, but this has yet to be verified, the Chinese make a lot of claims.
Vision: a and held, private comm with connection to one other anywhere in the solar system or even the universe, with no delays.
