Perfect quantum key distribution with almost classical devices

Hub investigators have published a new research paper exploring the implementation of quantum secured encryption through (almost) classical devices.  Sending private messages across long distances is possible using pairs of shared, secret keys, which hide data from everyone except the intended recipient. Secret key distribution is therefore essential for modern day society, where we depended […]

Visionary new approach for space-borne quantum technologies brings global quantum networking closer to implementation

Implementation of global-scale quantum communication networks is currently hampered by distance limitations affecting the quality of signals sent down standard optical fibre. Use of quantum repeaters can help to extend the transmission range, but the resulting technology requirements and costs are substantial. In a newly published paper, Quantum Communications Hub researchers from the University of […]

Quantum City launches new website to engage next generation of quantum scientists

Quantum City, a public engagement initiative set up by UK National Quantum Technologies Programme partners in 2018, has reached a new milestone in the launch of a new website (quantumcity.org.uk) aiming to inform and capture the imaginations of people interested in understanding more about quantum technologies. Quantum technologies will soon be used in our everyday […]

The Hub publishes annotated versions of NCSC’s technology assurance principles with relevance to the quantum communications sector

In late 2021, the UK’s National Cyber Security Centre (NCSC) published a White Paper outlining a new approach to technology assurance and plans for its implementation. This approach partly arose following the publication of the 2021 Integrated Review of Security, Defence, Development and Foreign Policy which emphasized the need for “cutting edge cyber capability” and […]
