A quantum security leap?
What is quantum security, what are the real world implications for the enterprise and is it really unbreakable? Davey Winder has been investigating...
Unless you happen to be Sheldon Cooper, the ubergeek character from the Big Bang Theory TV comedy show, the chances are that the mere mention of the word quantum either throws you into a fit of confused despair or science fiction inspired laughter.
Yet it was almost exactly two years ago now that a very real computer network was protected by supposedly unbreakable quantum encryption for the first time. Physics beats maths in the world of encryption for once. Bazinga!
It was back in October 2008 that the worlds of science and security collided with something of a big bang as a team of research scientists used a quantum cryptography implementation to secure a network consisting of 200km of standard commercial fibre optic cabling to connect six locations in and around Vienna.
