Professor Mark Hersam and his team have developed a simple, scalable strategy to make quantum light sources more precise and reliable. By coating tungsten diselenide with an organic molecule, they boosted single-photon purity by 87%, controlled photon color, and lowered activation energy—advancing secure quantum communications and ultra-sensitive sensors.Molecular coating cleans up noisy quantum light
