As near as I can make out, this involves the flipping of polarity of quantum pairs of quarks. When this was discovered, what, fifty years ago they said it violated the speed of light and action at a distance, because when one quark exited its state of uncertainty, its component twin instantly assumed the opposite polarity -- no matter how far away it was.
This sounded to me like utter balderdash. Obviously the final state was already determined, even if momentarily unknown.
Now they're calling this "quantum teleportation" even though nothing is teleported or moved through space. It seems like another case of young scientists, raised on too much Star Trek, using familiar and exciting terms to get funding from scientifically illiterate legislators/administrators, even though the terms are scientifically totally inappropriate.
Or at least to me that's what it looks like.
