Instant Quantum Communication Is Near

Posted by timothy on from the by-the-time-you-read-this dept.

fljmayer writes "In this experiment, researchers in Australia and Japan were able to transfer quantum information from one place to another without having to physically move it. It was destroyed in one place and instantly resurrected in another, 'alive' again and unchanged. This is a major advance, as previous teleportation experiments were either very slow or caused some information to be lost."

    This article is awful. Terribly written, incoherent and obviously inaccurate.

    This sounds like an extension of previous quantum state "teleportation" via entanglement. These are interesting phenomena, but cannot be used to transmit information faster than the speed of light.

    It's not really quite clear what the breakthrough is here. But I'm fairly certain it doesn't involve a group velocity (i.e. information transmission) greater than c.
