Quantum Teleportation Is a Real Thing
Quantum teleportation is a way of using entangled systems to send messages which are entirely secure. We now know that that's the same phenomenon as putting a thing into one black hole and having it appear through the wormhole coming out the other one. But nothing actually disappears and then reappears, but you put something in one end and an equivalent thing comes out at the other end. That's called quantum teleportation. And we can see in the lab that we can do it. You can't use it to send things faster than the speed of light. Still true. Oh, that's too bad,.
