Abstract: Abstract Solid‐state quantum emitters, such as nitrogen‐vacancy (NV) centers in diamond, offer a promising route toward scalable quantum technologies. However, their random spatial distribution and inherently broad dipole emission severely hinder high‐purity single‐photon extraction—particularly in… read more here.
