“Teleporting quantum information is now a practical reality,” asserts Deutsche Telekom. The firm’s T‑Labs used commercially available Qunnect hardware to demo quantum teleportation over 30km of live, commercial Berlin fiber, running alongside classical internet traffic. In an email to Tom’s Hardware, Deutsche Telekom’s PR folks said that Cisco also ran the same hardware and demo process to connect data centers in NYC.
90% accuracy is the difference between arriving safely at your destination and arriving as a headless corpse.
this is teleporting photons, not atoms.
though, this may actually be a step towards true holographic technology if they can teleport the photons in space and not just between consumer and emitter.
This is about “teleporting” information not physical material (if my understanding is correct)
What do you think teleporters do? They don’t physically move your body - they dismantle it and reconstruct a copy at the destination. The middle step is the moving of information. Transportation like in Star Trek is basically magic - The Fly is more accurate., and the fact that it failed to differentiate between the two organisms is a demonstration of a horrendous flaw in the technology. Although realistically he would have come out the other side as a gooey heap, because his DNA would have also been scrambled with the DNA of every microbe on his skin, his entire gut biome, and even the his eyelash worms - look it up.
Seriously, a person is a disgusting ecosystem just filled with all kinds of crazy shit. And that’s not even accounting for the cells in you with random-ass mutations from DNA transcription errors.
The only way for it to actually work world be to analyze the location and connections of every atom in the scanning area and then send that information to a machine that rebuild the scanning area exactly the same. And if you don’t destroy the original, you didn’t transport anything - you copy it.

Bit disingenuous to talk about teleporting things along a fiber line…
Also shows a fundamental misunderstanding of how quantum entanglement works…
But it’s actually pretty huge that they’re able to do this.
As someone who also doesn’t fully understand quantum entanglement… is it that when two particles are entangled and far apart, when we observe them they will always be in the same state? Is there any way to manipulate that state? If so, it seems like it would be pretty straight forward to use it for faster than light communications.
when we observe them they will always be in the same state?
The two particles are in different but directly related states. For example in some circumstances with two entangled photons, it will necessarily be the case that one photon has horizontal polarisation and the other vertical polarisation. The two will never have the same polarisation.
You can’t know which photon is in which state without measuring one. The effect of taking the measurement travels faster than the speed of light. Measurement is not manipulating though; you can’t say “I want this photon to be measured as vertically polarised”, you can only ask “what is the polarisation of this photon?”. So you can’t transmit information faster than light, unfortunately.
