HYBOXI- HYBrid MBE-CVD rare-earth doped Oxide films for on-chip optical quantum technologies

HYBOXI- HYBrid MBE-CVD rare-earth doped oxide films for on-chip optical quantum technologies

In the field of Quantum Technologies (QT), specially engineered solid-state materials – and their development – are essential to innovation. Uniquely successful amongst these material systems, rare-earth ions (REI) exhibit particularly long optical coherence lifetimes and record spin coherence lifetimes. Still, REI have yet to be integrated into practical and scalable quantum devices, and their optical and spin properties in thin films continue to lag behind that of their bulk counterparts. This project aims to develop epitaxial REI doped oxide films with limited structural defects in order to build a new generation of quantum photonic devices. Facilitating developments in both material science and device fabrication, this project will address fundamental challenges in quantum optics and contribute greatly to advancing a new field of research.
