Abstract (English)	With increasing amounts of data being sent and stored across networks, there is a pressing need to ensure data security. Quantum Key Distribution (QKD) provides two parties with a perfectly secure random key which can be used to encrypt and decrypt messages, offering a level of security beyond that possible with current systems. QKD technology could be used to support the competitiveness of European industry and provide improved data security in banking, commerce, government, and the transmission of personal data, such as medical records. However, to achieve this, measurement infrastructure and standards for quantum optical technologies, such as QKD, are needed. This project aimed to accelerate the development and commercial success of QKD technologies, through the development of metrological capacity in quantum optical technologies. It provided efficient, cost-effective measurement techniques for the development of counter-measures to hacking attacks on existing QKD systems, as well as the foundational metrology needed for next-generation entanglement-based QKD systems.
