First real-world use of quantum cryptography

From IET Engineering and Technology November 2007, "Swiss election marks 'first real-world use of quantum cryptography'". It was used to secure communication along dedicated optical fibre links used for counting ballots. The system was developed by University of Geneva spin-off company id Quantique. (The id Quantique Press Release.) I hadn't realised quantum cryptography was so close to reality.

An interesting quote in the piece, from Geneva State Chancellor Robert Hensler:
Information is the raw material of the State. Whether in the context of a political decision, a police investigation or hospital care, the State is both regulator of information exchange and a provider of information-based services.
