My research focuses on the architectures, technologies and control methods needed to build scalable, programmable and reliable optical and quantum networks. A central interest is reconfigurable quantum networking for quantum key distribution and multi-user entanglement distribution. I investigate quantum optical switching, entanglement routing and resource allocation, alongside architectures and protocols supporting entanglement swapping, quantum teleportation and quantum repeaters. The aim is to connect individual quantum devices into networks that can deliver useful services across local, metropolitan and wider-area infrastructure.

I also investigate the integration of quantum and classical communications, particularly how fragile quantum signals can coexist with high-capacity data transmission over shared infrastructure. My interests include conventional single-mode fibre, hollow-core and multicore fibres, and free-space optical links. This work examines transmission impairments, noise mitigation, optical switching and the trade-offs between network performance, flexibility and resource use. It also explores how quantum key distribution can be integrated with optical and future mobile networks to support secure communication services.

A further focus is intelligent and autonomous network operation using software-defined networking, artificial intelligence and digital twins. I develop approaches for service orchestration, resource optimisation and network stabilisation, together with timing, synchronisation and low-latency heralding and feedforward for quantum protocols. My interests extend to resource management and circuit scheduling for distributed quantum computing, linking application requirements with network capabilities. Across these areas, I combine modelling and algorithm development with laboratory experiments and demonstrations over deployed networks to evaluate performance under realistic operating conditions.
