Low-loss photonics for quantum networks

About the Project

Supervisory Team: Prof James Gates and Prof Corin Gawith

In the world of Quantum Technology every photon is precious. This project will create new ultra-low-loss optical components that will lead to advanced quantum memories, switchable delays, and the creation of large, entangled quantum states.

Unlike optical telecoms, where amplifiers compensate losses, in the world of Quantum Technology, every photon is precious. This project will create new ultra-low-loss optical components, including quantum memories and switchable delay lines, with the goal of reducing system-wide losses and allowing us to create large, entangled quantum states. This project will develop various technical approaches, including an all-optical fibre-based system and integrated atomic vapour devices.

You will have the opportunity to design, fabricate, and test these photonic systems and to work with experimentalists to validate their use in larger quantum systems. You'll join our interdisciplinary team of students, postdocs, and senior researchers developing systems for quantum technologies. You'll develop core components for interfacing quantum computers and networks using Southampton's state-of-the-art fabrication facilities.

If you are interested in computer modelling and have the required skills, the project can also be adjusted for this. If you are interested in quantum technologies, photonics, nonlinear optics, or micro-fabrication you would be highly suitable for this project. The Optical Engineering and Quantum Photonics Group offers a supportive environment for training and research, world-leading facilities and expertise, and extensive opportunities to collaborate with our industrial partners and academic researchers across the UK National Quantum Technology Programme.

Entry requirements

You must have a UK 2:1 honours degree or its international equivalent.

Fees and funding

Full scholarships include tuition fees, a stipend at the UKRI rate plus 10% ORC enhancement tax-free per annum for up to 3.5 years (totalling £22,858 for 2025/26, rising annually) and a budget of £4200 for things like conference travel.

UK, EU and Horizon Europe students are eligible for scholarships. CSC students are eligible for fee waivers. Funding for other international applicants is very limited and highly competitive. Overseas students who have secured or are seeking external funding are welcome to apply.
