First Secure Quantum Crypto Network Up and Running
John Lam was one of many readers to send in news that on Thursday, "at a conference in Vienna, Austria, as reported by the BBC, a European Community science working group built a quantum backbone using 200-km of standard commercial optical fiber running among seven sites and successfully demonstrated the first secure quantum cryptographic key distribution network. In addition, each of the seven links used a different kind of quantum encryption, demonstrating interoperability between the technologies. To paraphrase, the project focused on the trusted repeater paradigm and developed an architecture allowing seamless integration of heterogeneous quantum-key distribution-link devices in a unified framework. Network node-modules managing all classical communication tasks provide the underlying quantum devices with authentic classical channels. The node-module architecture uses a layered model to provision network-wide, end-to-end, provably secure key distribution."
You'll be able to tell if your web traffic has been snooped by the authorities because all your lolcats will arrive dead!
xkcd is almost always relevant
Wanted: Schrödinger's Cat. Dead and alive.
So, we have quantum computers with quantum networks doing quantum cryptography. What's next, buying music with quantum DRM, i.e. the song is both there and not there until the sound card observes it? ;)
No, xkcd is always almost relevant.
