During QIL 2018, we hosted working groups fromAirbus, BT and Leonardo. We were joined by almost 50 industry representatives and academic specialists to discuss the following topics:

Airbus discussed the use of quantum communication via free-space channels. This included links between satellites, airborne vehicles, and metropolitan stations to develop a quantum network. The group assessed the viability of using quantum encryption, such as quantum key distribution, to make these links reliably secure. We also explored the requirements of a quantum-ready device, such as satellites, and how classical and quantum communication can co-exist.

Near-term quantum technologies have the potential to benefit large scale networks. However, current UK fibre networks do not satisfy the requirements for communication of quantum states. In two working groups, we explored how BT can adapt their infrastructure to fit the demand of new quantum communications technology, as well as how quantum algorithms could be applied to computational problems for their networks.

Leonardo are interested in quantum sensing and timing. One working group explored how quantum entanglement might benefit laser range-finding techniques, making them more precise and robust. In the second working group, we explored the utility and viability of optical clocks, as well as topics related to their functionality.

Among working group leads, we were also joined by ADVA, Gemalto, Koruza, NPL, Redwave Labs, and academics from Universities of Bristol, Heriot-Watt, Oxford and South Wales.
