Arbitrarily structured quantum emission with a multifunctional metalens

Arbitrarily structured quantum emission with a multifunctional metalens Abstract Structuring light emission from single-photon emitters (SPEs) in multiple degrees of freedom is of great importance for quantum information processing towards higher dimensions. However, traditional control of emission from quantum light sources relies on the use of multiple bulky optical elements or nanostructured resonators with limited functionalities, constraining the potential of multi-dimensional tailoring.
