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 […]

First demonstration of enhanced security for random number generators

Researchers from the University of York and collaborators in China are a step closer to the commercialisation of next-generation random number generators (RNGs), a key technology used to ensure data security. Most of the world’s cybersecurity infrastructure is based on the exchange and use of digital cryptographic keys. RNGs are essential to this infrastructure but […]
