Experimental techniques in optical quantum dot control

Solid-state quantum emitters, particularly epitaxial quantum dots (QDs), are one of the most promising platforms of quantum light sources to realize a compact quantum photonic architecture. Optimizing the performance of QDs for such purposes involves both source engineering and photonic control aspects. In this technical review, we examine a broad range of photonic techniques to control light–matter interaction in QDs, from an experimental viewpoint. Achieving full control over photonic degrees of freedom will transform quantum dots from laboratory to standardized building blocks in photonic quantum systems.
