That's not entirely correct, they did use a fiber optic cable to transfer the data, as the more detailed article linked in another comment states. Quantum entanglement itself can't be used to transfer data; you still need to send the entangled particles through some physical means.
So what is being teleported? The state of the two entangled particles?
This highlights the problem with using that term. The two particles assume a state at the same time at a distance. It has 0% to do with the colloquial term.
Yes. Information is what's being teleported. The photons that carry the information still have to travel from sender to recipient but the information they contain doesn't exist until it is received. Like how Shrodinger's Cat is both alive and dead until you open the box to check.
I see. that makes more sense, thanks!
No problem! I love getting into the comments under articles on quantum stuff 'cuz the topic is weirdly unintuitive from the classical perspective and a lot of folks share some common misconceptions about jargon like "teleportation" and "entanglement". Please do ask if you've got any other questions! 😄
