摘要

The pursuit of high-quality single-photon sources has long been hampered by challenges in improving the performance and robustness. While traditional microcavity structures can achieve impressive performance, they suffer from extreme sensitivity to manufacturing uncertainty, structural disorders, and scatterings. Topological photonics potentially offers a powerful toolbox for solving these problems. A recent breakthrough by researchers from the Beijing Academy of Quantum Information Sciences, published in Light: Science & Applications, exploits a topological bulk state rather than the already reported edge and corner states to enhance the single photon emission for a quantum dot.
