Quantum Telecloning

February 18th, 2006 | researchmaterial

The first experimental demonstration of quantum telecloning has been achieved by scientists at the University of Tokyo, the Japan Science and Technology Agency, and the University of York.

Telecloning combines cloning (or copying) with teleportation (i.e., disembodied transport).

The scientists have succeeded in making the first remote copies of beams of laser light, by combining quantum cloning with quantum teleportation into a single experimental step. Telecloning is more efficient than any combination of teleportation and local cloning because it relies on a new form of quantum entanglement – multipartite entanglement.

Professor Sam Braunstein, of the Department of Computer Science at York, said: “Quantum mechanics allows us to do things which we previously thought were impossible. In 1998, I was involved in an experiment in America which was one of the first for quantum teleportation in which we transmitted a beam of light without it crossing the physical medium in between.

“This new experiment is an extension of that work. Whether it will change the world for individuals or is just of use to governments or big companies is hard to say. Any new protocol is like a new-born baby and it has to develop, but we know this one could be used to tap cryptographic channels. Quantum cryptographic protocols are so secure that they can not only discover tapping but also where and how much information is leaking out. Now, using telecloning, the identity and location of the eavesdropper can be concealed…”

  1. So, this means we can now make our own evil twin?
    ‘Bout damned time!

  2. Telepresence, and so forth. “Virtual Light” cycle

  3. I am so going to California to interview the Smiler’s wife. How come everything you write about happens eventually??? Can you predict me a larger wang?

  4. Didn’t you write this concept into Transmetropolitan, when Spider went to California “incognito” to visit the PResident’s wife?
    Oh Shit! I’m a fuckin’ fanboy! Just shoot me now……

  5. Isn’t this a little bit of blame-shifting as well? It doesn’t matter if it was predictable or not, or if the intentions by terrorist are known, because of the security failures on that day that would have prevented even a simple assault on one of those planes. If the Saudi’s had been caught going through the airports we’d be saying “well that’s why we have these measures”.

  6. fuck! stupid hand eye co-ordination screws me again
