Project: Metrology for industrial quantum communication technologies

Quantum communication technologies such as Quantum Key Distribution (QKD) can improve the security of the ever-increasing amount of sensitive information that is stored, transferred and accessed over computer networks. The unique feature of QKD is that, when implemented correctly, the system guarantees that the encryption key has not been intercepted. It works by transmitting information in a photon in a particular ‘quantum state’ and then detecting if an intruder has disturbed that state. In theory it is extremely effective but there are no agreed methods to demonstrate that practical implementations are robust. This project developed a series of measurements that are sensitive enough to characterise the properties of individual particles of light, as well as the single-photon detectors which QKD systems use. The project has laid the foundations for a European measurement infrastructure able to validate the performance of QKD systems, and technologies that use and manipulate single photons, important in the development of next-generation communication systems and quantum networks.
