Quantum Key Distribution (QKD) provides a provably secure approach to share keys used to encrypt secret information by transmitting single photons [1] . This is one of the first commercial quantum technologies available, and Bristol is heavily involved in UK Quantum Communications Hub to develop a chip-based approach and integrate them in our 5G-UK network testbed.

The EPSRC quantum communications hub

Timothy P. Spiller

The Quantum Communications Hub is one of four Hubs comprising the research and development end of the UK National Quantum Technologies Programme. This programme is now in its second phase (2019-2024), following a successful first phase that ran 2014-2019. Our Hub provides the UK focus for the quantum communications sector. In this talk I'll provide a brief overview of the Hub's phase 1 developments, which mainly concentrated on progressing quantum key distribution (QKD) towards wider application. The grand vision of the phase 2 Hub is integrated secure quantum communications at all distance scales. For practicality and flexibility, this involves free-space communications at the shortest distance scales, fibre-based communications at the metrolpolitan and inter-city distance scales covered by current fibre networking, and free-space communications to support the very longest distances required for global reach. I'll outline the Hub activities on short-range consumer QKD, fibre networking and long distance satellite-to-ground QKD. I'll also cover our work on new protocols, hybrid secure communications, standards and components. http://www.quantumcommshub.net/The Quantum Communications Hub is one of four Hubs comprising the research and development end of the UK National Quantum Technologies Programme.
