Unbreakable
Within three years, companies could be using quantum cryptography to protect sensitive messages. British researchers say they are close to producing an off-the-shelf system that exploits quantum physics to create a secure communications channel. The system encodes bits of information on individual particles of light. This week, the researchers demonstrated their system working over fibres 100 kilometres in length. [BBC]
