Boffins have moved one step closer to a practical implementation of the Holy Grail of encryption - quantum cryptography - by exchanging keys across a 67km fibre optic network. Until recently, the idea of quantum key distribution has been tested only in the physics laboratory. Now, a team from the University of Geneva and Swiss electronics company id Quantique have demonstrated what is described as the "first fully integrated quantum cryptography prototype machine" across a telecommunications network. This advance is limited to fibre optic networks but other scientists are beginning to consider how quantum keys can be shared over satellite or wireless networks.
