This project will investigate the use of quantum photonic sensors for harsh environments in minerals processing. The inherent durability and abrasion resistance of Silicon Carbide (SiC) makes it an ideal candidate for deployment into these environments, uniquely coupled to its maturity in wafer-scale microfabrication processing and ability to host colour centres with single photon emission and strong spin-photonic interfacing. Colour centres such as silicon vacancies and PL5-7 centres can be addressed at elevated temperatures through, for example, optically-detected magnetic resonance measurements to sense temperatures, magnetic fields and mechanical effects like material strain with high resolution and precision. As a wide-bandgap semiconductor, microelectronic and MEMS devices can be engineered on-chip to provide integrated control and monitoring capabilities of the quantum sensor. Further, the emerging quantum-grade SiC-on-insulator chip platform could provide an avenue for developing photonic integrated circuits to more effectively excite and read out sensors based on individual or small ensembles of colour centres.
