Slashdot Mirror


Laser Beam Teleported

Michael Wardle writes "ABC Australia reports that a team of scientists from the Australian National University have successfully teleported a laser beam. It seems that teleportation of solid bodies is still a way off, but at least we're a little closer to Slashdot's favorite super power." Another Australian newspaper has a more detailed story.

  1. Teleportation, or recreating? by Wire+Tap · · Score: 4, Informative

    It seems to me, that there is a huge difference:


    Team leader Dr Ping Koy Lam says it involved creating a laser beam, its disembodiment and the recreation of the original beam in a different location.


    To me, that sentence can be translated as such:

    Team leader Ping Koy Lam says it involved creating a ball point pen, its destruction and the recreation of the same ball point pen using a factory blueprint in a different location.

    This isn't the first time I've read about "teleportation" of some particle or another, when it seems that they are simply re-creating, mirroring if you will, the particle(s) quantum states in another place. That's not teleporting - that's mimicing.

    The URL you have provided is for a page published by a student undertaking a first-year physics course. Whilst it may (or may not) contain some good content, I doubt the student is part of the research team, and the page should not be treated as authoritative.

    The page at http://photonics.anu.edu.au/qoptics/ is somewhat more official.
