This project aims to explore the use of topologies for robust communication in free-space and optical fibre. Current quantum entangled states suffer from real-world sources of noise, which tend to degrade the quantum link. This project focusses on engineering the quantum wave function, allowing the entanglement to remain fragile while preserving the quantum information. This could be used to overcome noise in global quantum networks and quantum computers.

This project aims to develop compact, chip-integrated quantum random number generators (QRNGs) and nanophotonic single-photon sources using nitrogen-vacancy (NV) centres. The QRNG demonstrator is based on a plasmonic nanowire architecture, designed to generate high-speed, intrinsically secure random numbers using quantum photonic processes. The single-photon source is designed for use in quantum communication, entanglement generation, and quantum sensing. These devices will be designed and tested for high performance, miniaturisation, and integration into quantum networks.

This project aims to create an interactive learning tool for schools and universities to introduce students to quantum communication and cryptography. Highschool learners will interact with a cryptography game and compare messages using traditional cryptography and the Quantum Key Distribution (QKD) system. The university student will be introduced to the construction of a QKD system based on the BB84 protocol, utilising decoy states and facilitating learning of the system’s different aspects.
