“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.

Nope, the actual information must still be transported via a classical no quantum (and trusted) channel so that both ends can match their statistics and thus deduce the crytographic keys from the qunatum signals. And thats it what its all about: key exchange

thanks. I had forgotten about that I think mainly because I can't wrap my mind around how it works like if its intercepted and used then it will confirm that its void and produce a new one or such.
