Atoms and molecules are too small to act as efficient antennas for their own emission
wavelengths. By providing an external optical antenna, the balance can be shifted; …

A two-level atom cannot emit more than one photon at a time. As early as the 1980s, this
quantum feature was identified as a gateway to 'single-photon sources', where a regular …
