A group which in 2012 gave a laboratory demonstration of quantum key distribution (QKD) using lit fibre has taken its next step, demonstrating its technology in a field trial in the UK. Two years ago, the National Physical Laboratory (NPL) led a project that achieved a 500 Kbps key distribution rate on a 50km fibre that was also carrying 1 Gbps of conventional optical network traffic in both directions. Now, the NPL’s group has conducted a field trial of the technology using a BT link between its Adastral Park laboratory in Suffolk and another BT site in Ipswich, about 18 …continue reading
