    Specifically, scientists have worked out how to teleport information almost instantly and over any distance – without needing any future technology

    Either this is a world changing discovery that breaks everything that I’m hearing about only in… checks… the BBC Science Magazine

    Or… it’s complete wank clickbait nonsense

    OH WHICH IS IT GOING TO BE?!

      TLDR: They sent information through a fiber-optic cable using fewer photons per bit than before.

      They only transmitted information, not any non-photon particles. They didn’t exceed the speed of light, or exceed the speed of light through fiber-optic cable.

      The second one, of course:

      the new research proposes that the breakthrough could make these communications super secure and nearly instantaneous – limited only by the speed of light.

      (enphasis mine)

      So, yeah, we didn’t break any laws of physics.

        Well… I think the idea is once you can reliably send a photon, you can start sending entangled photos. Then you can use those to build networking hardware that transmits bits instantly.

          I’m pretty sure it’s impossible to transmit bits “instantly” i.e. faster than light under the current quantum theory or relativity theory, you can’t transmit information faster than the speed of light. If somebody found a way to do that, we’d be rewriting the laws of physics, and that would be a big deal for sure.
