Flexible Quantum Wireless System

Quantum Key Distribution (QKD) is a cryptographic scheme which provides an unrivalled level of data security. This project specifically investigates practical application of QKD in securing short-range wireless communication between a terminal such as an Automatic Teller Machine (ATM) and a handheld device (e.g. mobile phone), complementing the existing Theme 1 activity in the Hub. This quantum security model can be extended to mobile phone payment and other indoor wireless applications. The consortium (the Universities of Bristol and Oxford [NQIT Hub]) has existing effort in quantum wireless security. Oxford has a project (funded by Innovate UK) in specifically studying the feasibility of a quantum wireless system with hand-movement tracking capability; while Bristol (Quantum Communications Hub) is leading the Theme1 Hub work in developing next generation credit card with quantum enhanced security. Both partners are working together to develop a flexible platform for future quantum wireless technology.
