The rise of quantum computing could see the UK become a leading provider of secure electronic communication.

Quantum key distribution is the term given to a type of communication that uses photon particles as a protective code, taking the form of a signature. If a transmission is intercepted by a third party, the particles will change ­ alerting the sender that someone has interfered. This technique could vastly improve the security of electronic communication.

Equipment relating to quantum processes is already being sold, and the first usable systems could be made available by later this year, said Charles Ross of London Quantum Networks.

“The problem is getting the technology into the marketplace,” he said. “The UK can become the leader in this market. The opportunity is there, if we get off our backsides and do it.”

London Quantum Networks is working with the National Physical Laboratory to advise the government on its possible use of quantum technology.
Ross was due to address the Cyber Security Knowledge Transfer Network in London today (Thursday).
