QUANTUM OPTICS

The quest for a perfect single-photon source

Nature Photonics volume 13, pages 734–736 (2019)Cite this article

Subjects

A quantum-dot-based single-photon source with a polarized single-photon efficiency of 60% and an indistinguishability of 0.975 is demonstrated by introducing a small asymmetry in a photonic cavity structure.
