About the project

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, reducing losses and allowing us to create large, entangled quantum states. In particular, the project will develop quantum memories and switchable delays.

You will develop core components for interfacing quantum computers and networks using Southampton's state-of-the-art fabrication facilities.

In particular, the project will develop quantum memories and switchable delays.

This project will look at various approaches, including an all-optical fibre-based system and integrated atomic vapour devices. You will design, fabricate, and test these photonic systems in this project. You will also work with experimentalists to validate the system. 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 and micro-fabrication, you would be highly suitable for this project. You will benefit from our world-leading expertise in these fields and enjoy working in a highly supportive environment in the Optical Engineering and Quantum Photonics Group, while collaborating with partner groups around the country within the UK National Quantum Technology Programme.
