Abstract Solid‐state quantum emitters, molecular‐sized complexes releasing a single photon at time, have garnered much attention owing to their use as key building block in various technologies. Among these, emitters hexagonal boron nitride (hBN) emerged front runners with superior attributes compared other competing platforms. These are attainable thanks the robust, two‐dimensional (2D) lattice of material formed by extremely strong B─N bonds. This review discusses fundamental properties hBN and highlights recent progress field. The focus is on fabrication engineering these facilitated state‐of‐the‐art equipment. Strategies integrate dielectric plasmonic cavities enhance optical summarized. latest developments new classes spin‐active defects, predicted structural configurations, proposed suitable applications examined. Despite current challenges, steadily become promising platform for information science.
