Practical Quantum Cryptography

Posted by timothy on from the next-year-it'll-be-in-wristwatches dept.

Alien54 writes: "Saw this on Eureka Alert: A commercially available system for quantum key distribution and cryptography has been released by a spin-off company from the University of Geneva. The system has been tested over distances up to 70km (from Geneva to Lausanne) through standard optical fiber cables and connects to PCs via USB ports. Transmission rates of about 60 bits per seconds were achieved, sufficient for key distribution. You can see the original abstract here, which also has a link for download of the paper in PDF, Postscript, and other formats."

    I'll bet a shiny quarter that your upper classes pay more than ours do (and that you have a higher capital gains tax).
