By using tiny light sources that are no larger than a few nanometers in diameter. Examples of these types of light sources are fluorescent molecules, nanoparticles, and quantum dots.
The JQI work uses quantum dots which are tiny crystals of a semiconductor material that can emit single photons of light.
