Summary on Grant Application Form |
Quantum communications can guarantee the security of data transmission. Although the technology to achieve this is
proven over dedicated point-to-point links, the full potential will only be realised with multi-user quantum networks.
Quantum relays offer a platform which can provide this, allowing quantum keys to be teleported across fibre-optic networks.
Commercial uptake requires practical entangled light sources operating within the optimum telecom wavelength band
around 1550 nm, and thanks to an established InnovateUK funded project, such sources are emerging for the first time.
Our vision is to construct and operate such a quantum relay, making practical quantum networks a realistic opportunity. By
combining the proven expertise and experience of the partners together with a challenging workplan, we will create an
improved generation of entangled photon-pair light sources engineered to interact with laser light. Epitaxial material will be
grown at the University of Sheffield and processed into a range of novel device structures at the University of Cambridge. A
prototype quantum relay will be delivered by TREL, which will leverage our unique entangled light sources, to teleport
quantum information encoded on laser beams, as demonstration of a practical quantum network.
