This project, within the EPSRC Centre for Doctoral Training in Quantum Technology Engineering at the University of Southampton (https://qte.ac.uk), carries a UKRI TechExpert enhanced annual stipend around £31k for UK students. While researching the project outlined below you will also receive substantial training in scientific, technical, and commercial skills.

Project Description:

A novel nano-opto-electro-mechanical (NOEM) tunable SiC entangled photon source will be developed for future on-chip quantum photonic circuits technology. Design optimisation, device fabrication and single photon measurements are planned to prove the working principle and tunability of the device.

The aim of this project is to establish a solid technological platform to generate an entangled pair of photons in a controlled manner for future advanced quantum information and communication technology. Opto-Electro-Mechanical interactions are employed to control the timing of single photon emissions and to regulate the level of the entanglement of photons coherently generated from two adjacent photon sources. Silicon carbide is chosen as a platform material for future integrated on-chip reconfigurable quantum information and communication circuits. At the end of the project, a novel tunable entangled photon generator will be demonstrated on a silicon-based substrate. The outcome will make significant contribution not only to inspiring discrete photon generation device research but also to opening up a path to on-chip photon-source-integrated quantum circuit technologies. This is a collaborative project between the University of Southampton and the Institute of Science Tokyo.
