Ryan Mandelbaum explains this phenomenon for Gizmodo:
So, here’s a simplified version of quantum teleportation. Let’s say you take a red and a green ball, put each randomly into one of two bags, and hand one bag to a person on the ground, and another to a person at the satellite. But on the ground, there’s a second bag, containing another green ball that the folks on the ground want to “teleport” to the satellite, without anyone else knowing it was green. Quantum teleportation says that, with the entangled link already set up, the folks on the ground have only to open both of their bags, then call the satellite on the phone and say either “same” or “different.” If the ground observer opens both bags and sees both balls are green, she can just say “same” to the satellite. The satellite will then open his entangled bag, which has to have a red ball, which means the ground must have had the green ball in the entangled bag, and that means the secret ball had to be green.
Thus, the state of the secret ball is “teleported” to the satellite.
