“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.

    I’m sorry, but all of special relativity disagrees with you.

      The only way that an observer can see a message arrive first before it was sent is if that message was also faster than light.

      The propagation of the information that the signal was sent will be travelling before the information of the result starts to propagate. So even if the message is sent equal to light speed, there’s only one point on the two expanding spheres where the cause and effect appear simultaneously. That message you’re observing would have to move quicker than light for any observer to be overlapped by the effect bubble before the cause bubble reaches them. Both of those bubbles expand at the same rate.

      How are you beating an ftl signal with your own ftl signal if you’re relying on information that is moving at light speed to react to?
