Quantum Cryptography: 100km Barrier Broken

Posted by timothy on from the speaking-of-crypto dept.

jdfox writes "Toshiba Research Europe have just demonstrated quantum crypto over 100km fibre links. Sounds like there's still a fair bit of work to be done before it leaves the lab, but it's amazing that they've got as far as they have. There's another article about it, though still not much technical detail, here on the BBC and here on The Register."

    I mean, I don't know many labs that are 100km long. I've heard of mile long labs at NASA or the NSA or somewhere, but not 100km.

    Bleh, sorry for the lame joke, I'm drunk.

    Do you think these people are idiots?

    NO YOU COULDN'T! THAT'S THE WHOLE POINT!

    Read up on your physics, boy.
