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."

    That must be a big lab! Or maybe they had 100km of fibre and they just looped it round and round and round. ;)

    How could it not have left the lab? Is Toshiba's lab 100KM long? That's a pretty huge lab!

    Imagine, all you will need for you own photon ray gun/torpedo is a network cable with signal. Looks like the geek shall inherit the earth after all.
