    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.

          Quantum mechanics do “bypass” the speed of light from my understanding.

          It’s not that you’re moving anything or actually bypass the speed of light. You just have basically a value that’s “entangled” so when it’s changed in one place it’s instantly changed in the other; it’s really freaky.
