Novel Materials for Quantum Speaker: Hannah Stern Lecturer/Royal Society University Research Fellow, University of Manchester

Abstract:

Quantum networks and sensing require solid-state spin-photon interfaces that combine single-photon generation and long-lived spin coherence with scalable device integration, ideally at ambient conditions. Despite rapid progress reported across several candidate systems, those possessing quantum coherent single spins at room temperature remain extremely rare. In this talk I will report quantum coherent control under ambient conditions of a single-photon emitting defect spin in a a two-dimensional material, hexagonal boron nitride. I will show that the carbon-related defect has a spin-triplet electronic ground-state manifold. I will demonstrate that the spin coherence is governed predominantly by coupling to only a few proximal nuclei and is prolonged by decoupling protocols.

Biography:

Hannah Stern has recently started as a Lecturer across Physics and Chemistry at the University of Manchester, where she is also a Royal Society University Research Fellow (URF). Prior to this, she was a URF and postdoctoral fellow in the Cavendish Laboratory at the University of Cambridge, where she also completed her PhD. Her research group focusses on the identification and development of new material systems for quantum optical technologies.
