nanoAGILE (Axially Graded Index LEns) for quantum technologies

This project is part of the EPSRC Centre for Doctoral Training in Quantum Technology Engineering at the University of Southampton (https://qte.ac.uk/). In addition to the research project outlined below you will receive substantial training in scientific, technical, and commercial skills.

Current photonic quantum systems suffer from the poor brightness of the single photon sources used as a source for the qubits. The PhD position will explore ways of enhancing light extraction from photon sources and ways to detect meaningful qubit information. This project is a combination of physics, engineering, materials, and advanced device fabrication that will be essential in the feasibility and scale up of quantum technologies. 

Can novel device designs, materials, and fabrication techniques accelerate the development of quantum computing in the near future? 

A challenge faced by photonic quantum systems is the poor brightness of the single photon sources used as a source for the qubits. A similar problem has already been solved in the macroscopic regime: the AGILE (Axially Graded Index Lens) light concentrating device. This project would be a collaboration between the group of Dr Nina Vaidya in the School of Aeronautics and Astronautics which has developed the AGILE device, and that of Dr Alberto Politi which has extensive experience in nanophotonic device fabrication.

This PhD project will cover design, fabrication, and testing of quantum devices  created with novel materials and fabrication processes. The student will have a chance to learn and contribute to the quantum era and explore light-matter interaction at the quantum level. These topics align well with future careers in academia, research, as well as the national and international engineering companies and start-ups.
