This is correct. I'll quote the article here: "What happened is the instantaneous and disembodied transfer of the photon’s quantum state onto the remaining photon of the entangled pair, which is the one that remained six kilometres away at the university,” says Tittel". So teleport in this case doesn't really mean teleport, it just refers to the "teleportation" or transfer of a quantum state.
- j1vms 10y agoI am not a career physicist, but have read much and thought deeply about these things. > So teleport in this case doesn't really mean teleport I would disagree with this statement. For all intents and purposes, the photon receiving the "transfer" is now indistinguishable from the photon that was transferred, before the event took place. That is to say, it has a completely identical quantum state following the transfer, and the "original" photon no longer has that "original" quantum state. They are only separate in space, and the transfer event took place at a defined "instant in time". It is is indeed ok to call this teleportation as (although this might seem odd in the practical sense) it is not possible to prove that the original photon was not teleported through space-time.
