Synopsis: 

Optically addressable spins in materials are important platforms for quantum technologies, such as repeaters for quantum networks. Identification of such systems in two-dimensional (2D) layered materials offers advantages over their bulk counterparts, as their reduced dimensionality enables more feasible on-chip integration into devices. In this talk I will introduce a two-dimensional material that hosts bright single photon emitting defects: hexagonal Boron Nitride (hBN). I will show our recent results of room-temperature optically detected magnetic resonance (ODMR) from single atomic defects in hBN. These results represent the first identification of room-temperature ODMR for single defects in a van der Waals material and offers a promising route towards realising a room-temperature spin-photon interface for future quantum technologies.

Biography: 

Hannah Stern is a postdoctoral researcher in the Physics Department at the University of Cambridge, working on new materials for future quantum technologies. She completed her PhD at the University of Cambridge on the topic of ultrafast dynamics in molecular semiconductors for higher efficiency solar cells, under the supervision of Prof Richard Friend. Subsequently, as a Junior Research Fellow at Trinity College, she shifted focus to study the quantum emission properties of two-dimensional materials within the group of Prof Mete Atature. In October 2022, Hannah will be starting a Royal Society University Research Fellowship.
