Abstract
Perovskite quantum emitters

The development of many optical quantum technologies is dependent on the availability of solid-state single quantum emitters with near-perfect optical coherence. Light-emitting defects in diamond and quantum dots grown by molecular beam epitaxy have demonstrated transform-limited emission linewidths. However, they are limited in terms of production scalability and reproducibility between individual emitters. Utzat
et al.
now show that perovskite quantum dots can overcome these limitations and provide unprecedented versatility for the generation of indistinguishable single photons or entangled photon pairs for quantum information processing.
