The two organisations say that their quantum cryptographic system is a success, and could have important implications for optical fibre networks already in use. The data was sent along 200 meters of optical fibre at a rate of one kbps. Not exactly fast, but there we go. The researchers reported a quantum bit rate error of one percent, which was kept low by the ability of the system to compensate for fluctuations in the phase and polarisation of the light. <SNIP> -- ----------------------Kaos-Keraunos-Kybernetos--------------------------- + ^ + :Surveillance cameras|Passwords are like underwear.
