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.
