This milestone achievement shifts quantum communications from an experimental lab technology towards something telecoms providers can deploy. Key implications are expected in distributed quantum computing , quantum-secure communication, quantum sensor networks, and cloud-based quantum services.
As per the intro, Cisco used the same hardware from Qunnect to run a similar demo in NYC. We last reported on Cisco’s quantum internet efforts back in November last year, when it announced plans to jointly build a distributed quantum computing network capable of linking fault-tolerant systems over long distances, with the help of IBM .
Experts from Deutsche Telekom, Qunnect, and Technical University Dresden will be available for discussion at MWC Barcelona, on March 03 from 15:30 – 16:00 (CET). Deutsche Telekom will also have a ‘Quantum Teleportation’ showcase at its booth.

usertests 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. However, in both the Berlin and NYC demos, the qubits didn't travel through the existing fibers; they teleported from one end to another. Qunnect’s Carina platform, which integrates an entanglement generator, producing pairs of quantum-entangled photons for distribution over telecom fiber. It "teleported", without traveling through fiber, but it requires fiber. Hmm. I wouldn't put much stock into quantum claims in the popular press. The results are what matter. It's going to enable new encryption/security schemes at a minimum. Let's see some neutrino-based high accuracy quantum communication. That would be amazing. Crazyy8 said: The Ansible. We need it to go faster than light to qualify. Reply
artk2219 usertests said: We need it to go faster than light to qualify. Also, wireless. That said, it would still be hugely helpful if its lagless to a receiver, then speed of light post receiver. Incredibly low lag drone control on the other side of the planet would be a possible use case, high frequency trading, gaming lol. Pretty much anything that needs super low latency could benefit.

ThisIsMe usertests said: We need it to go faster than light to qualify. The photons did have to initially travel before the teleportation experiment proceeded. They created pairs of entangled photons, sent one of each pair through the fiber like usual. Once it got to the other end the instant “teleported” data communication test proceeded by manipulating one of the paired photons and observing the other one for the changes. Reply
_Shatta_AD_ LOL Quantum Teleportation… that's a click bait way to call it. Quantum communication has been around for about a decade based on 'quantum pair entanglement' and China has been achieving secure data transmission over thousands of kilometers, both via satellite as well as existing and dedicated fiber line. Nothing new here! Reply
Zoolook13 The new thing is that they made the exchange on "public" fiber, its quite significant, the difference in cost and utility is incredible compared to dedicated fiber or dedicated satellites. That you didn't get that is sad for you, for everyone else its a huge step closer to usable quantum encryption. Reply
bit_user usertests said: It "teleported", without traveling through fiber, but it requires fiber. Hmm. They're saying the information didn't transit the cable, but obviously the entangled photons did. If you weren't transmitting information via entanglement, then you're not teleporting anything. usertests said: We need it to go faster than light to qualify. I'm no physicist, so I can't really follow these arguments, but Wikipedia is claiming that it's not possible. https://en.wikipedia.org/wiki/Faster-than-light_communication#Quantum_nonlocality Reply

Incredibly low lag drone control on the other side of the planet would be a possible use case, Even if the superluminal communication aspect turned out to be possible, entanglement couldn't be sustained for durations relevant to remote control. You need a fiber link or laser beam, for continually refreshing the pool of entangled photons. The main use case seems to be quantum communication, but the article also mentions quantum clocks, quantum computers, and quantum sensors (not that I know what would be an example of such a sensor).

Nothing new here! What's new is that they demonstrated it over existing fiber networks. Says so, right in the headline. Reply
