Diabolical points (DPs) introduce ways to study topological phase and peculiar energy dispersion. Scientists in China and partners from the United Kingdom demonstrated DPs in strongly coupled active microdisks. A new macroscopical control of backscattering based on the competition between defects and quantum emitters was used to achieve DPs. This work paves the way to integrate DPs and more exotic phenomena into quantum information processes with quantum emitters, and will inspire further research with DPs.
