You know, in a lot of sci-fis its not implied that teleportation is faster-than-light. Quantum teleportation does meet what does seem to be universal about "teleportation" though, which is that the "original" is necessarily destroyed. That is, it takes a thing, and moves it to another location, rather than copying it.

As far as I can tell, it just replicates the state of a particle in a remote location, using another particle of the same kind. So state is being transfered (i.e., information), but not matter, and nothing is being destroyed. I might be wrong about this, but that's what someone who explained it on hn said.
