The former is called “superdense coding” and the latter is called “quantum teleportation“. The guy who named it “quantum teleportation” and not the “2 bits = 1 qbit theorem” is a jerk. The discovery, and more importantly the subsequent naming, of quantum teleportation lead to a new (false) hope that entire objects might be teleported. Quantum teleportation (stupid name) allows you to get around this problem. 3) Alice keeps coins A and B, and Bob takes coin C as far away as he likes.
