"Novel quantum devices based on atomic vapour cells"
Photonic quantum devices based on atomic vapours at room temperature combine the advantages of atomic vapours being intrinsically reproducible and highly nonlinear – even on the single photon level - with scalability and integrability. We show the integration of photonic and electronic components into vapour cells and a first demonstration of an on-demand single-photon source based on four-wave mixing (FWM) and the Rydberg blockade effect. In the future integrated optical and electronic circuits in atomic vapour cells will enable applications in quantum sensing and quantum networks. As an example we discuss a new approach to molecular trace gas sensing.
