    The Unknown State Of A Photon Says "What?"

    Booyah.
    This pleases me greatly. Zap a set of three protons with an unknown state of a fourth, and learn about that unknown state by testing two out of the set of three.

    The third photon be all like "Shut yo mouths, hos!" And the other two be all like "Whatever! We do wha' we wan'!"

    Re: The Unknown State Of A Photon Says "What?"

    I need to stop reading crazy articles posted by pokerface this late. They speak of these "Quantum networks" in the future. Can't imagine what kind of whacky things they will have when i'm a grumpy old man.


    I love gaming, mmmmmmmm

    This is pretty cool. When transistors were being developed for computing it wasn't a very high scientific priority and it took many years for developments to be practical for the average Joe. I think that now, unless the military somehow grabs it and keeps the tech a secret, we're going to continue to see these developments very quickly as consumers. I'm ready for my AMD Athlon Quantum 1.4 GoogleHertz CPU...

    Ah yes, but then there's the laws of thermodynamics to worry about. Could you have a processor that fast? Maybe. Would it fry a city block? I haven't done the math (and won't!) but you're talking about a lot of energy and a lot of heat.

    The really cool application for this sort of system lies in the fact that the distance between the photons is arbitrary. They can be on opposite sides of a lab or opposite sides of the universe and yet remain the same "system", so when you know the states of part of the system, the states of the other part of the system instantaneously snap into being, even though they may be light years apart.

    So this enables faster-than-light transmission of information???

    Re: The Unknown State Of A Photon Says "What?"

    No. Relativity still holds.

    Uh...bear in mind that I spent my entire college career studying quantum mechanics and its philosophical implications and I don't have a clue about quantum mechanics. After a while you just stop trying to understand "what it all means" and pay attention to the math, which is also fun and interesting, and plenty challenging in itself. All of that is to say that I'm not going to be able to explain much here and don't claim to really understand it more than to say "you have no idea how weird it gets"!

    The EPR experiment attempted to challenge QM by showing how its predictions either violated relativity by allowing fast-than-light "transmission" of information or revealed that there must be "hidden variables" that, if known, would allow us to predict individual particles' behavior. Bell's Inequality debunked that interpretation and showed that the world is even stranger - that until tested, particles have no state. The act of testing causes that property to snap into existence. Sort of.

    Hmm, this site seems to have some basic info about this. http://en.wikipedia.org/wiki/EPR_paradox

    This site seems a little muddle-headed but has some good points:
    http://home.ecn.ab.ca/~jsavard/science/eprint.htm

    Search on EPR experiment, Bell's Inequality, bone up on your math, etc., for more info. It's a weird little world, that quantum world.

    We need to build an armory, then an observatory, and then research phase tech.
