Overview

Light is an ideal carrier of quantum information as photons are fast, cheap and easy to encode with quantum-bits carried in their polarisation, phase, time or path degrees of freedom. This project will work with a light source based on a single Indium-Gallium-Arsenide semiconductor quantum dot, as these can offer > 99% spectrally pure photons at high efficiency .

This project is funded by the UK National Hub in Quantum Computing and Simulation (Hub-QCS). The source will be produced in Cardiff’s Institute for Compound Semiconductors cleanroom and tested in our new optical labs. The focus of year 1 will be increasing the efficiency and purity of the source through design and experiment. In Year 2 you collaborate with partners in the Hub-QCS to demonstrate re-routing of photons in prototype network. In Year 3 you will build on previous research of the group demonstrate non-linear optical effects in the device.

Optical characterisation will be carried out in the newly established Quantum Technology labs with access to > £1M of equipment, including photo-detectors sensitive to the arrival of single photons, ultrafast electronics, high coherence lasers and cryogenic equipment. Practical lab skills will be gained including Labview programming, error analysis and data processing.

In addition, you will have access to the Institute Cleanroom to fabricate samples. This is a world-class facility run by a team of skilled technicians. In 2021, the group and cleanroom will relocated to a new £100 million facility on Maindy Road, resulting in a significant expansion in lab space.

The position is within a group supervised by Dr Bennett, with the support of 2 experienced post-docs and 3 PhD students. An exceptional level of training and support will be given to the candidate on a day to day basis in a friendly and open working environment. He/she will have a desk in an interdisciplinary research office with other Post-docs/PhD students from the schools of physics and engineering. To enable integration within the research culture of the university the he/she will attend Quantum-Team meetings (Mondays), Condensed Matter Seminars (Wednesdays) and the group Journal Club (Thursdays).

The group is fully committed to equality, diversity and inclusivity.

Accreditation

This studentship is funded by the National Quantum Computing and Simulation Hub (QCS-Hub) a £30M 5year project funded by EPSRC as part of the UK national Quantum Technology Initiative. Strong collaboration with other partners of the QCS-Hub is expected in the form of extended visits, sample exchange and joint publications.

Programme Structure

The candidate will uncover new science in a fast-moving research field, which will lead to great publications and opportunities to travel to international conferences and the main supervisor’s collaborators in the UK and EU. Regular opportunities to practice presentation and technical skills in Cardiff and at externally will result in a well-rounded education. In addition, much sought after cleanroom fabrication skills will enhance employment opportunities.This studentship is funded by the National Quantum Computing and Simulation Hub (QCS-Hub) a £30M 5year project funded by EPSRC as part of the UK national Quantum Technology Initiative.
