This is, very confusingly, "teleportation of the quantum state". Not unlike how merging a pull request is "teleporting the software state of your repo", but instantaneously. Essentially this is just entanglement at 6 kilometers, described by a blustery article.
- semi-extrinsic 10y agoNo, "quantum teleportation" is a specific technical term for a type of communication that involves both entanglement and a classical communication channel to together create a secure communication channel. https://en.wikipedia.org/wiki/Quantum_teleportation https://en.wikipedia.org/wiki/Quantum_teleportation
- das3ddddddd 10y agoThe purpose of quantum teleportation is the teleportation of quantum information. Teleportation is not necessary to the creation of a secure communication channel.
- smsm42 10y agoNot sure about "instantaneously" part. It's more like I send you a pull request and then I apply it to my repo and tell you to apply it to your repo and you get your repo in certain state which I knew upfront. Repo state teleportation! Yeah, it know it's not exactly that either, but it's about as magical as that, AFAIU. Which doesn't say it's not useful - ability to merge pulls and get all the repos in certain state is hugely useful - but calling it "teleportation" implying that we're on the verge of being beamed up and down like StarTrek characters sounds a bit more pompous than warranted.
