It's a well known fact (since Plank and Einstain) that photons have
quantized energy:
The energy of a single photon is equal to: hc/l, where h is the
Plank's constant, c is the speed of light in the vacuum and l is the

When you desing a light source you can control the total emitted power
(total energy/time) and the wavelength (the 'color' of the light).
Since the total energy emitted in a given time interval is just the
sum of the energy of all photons emitted in that interval, you can
simply calculate the average number of photons per interval: n = El/
hc, where E is the total energy.

Therefore, by keeping a low total power and/or a low wavelength you
can archive a small number of photons per time interval. In
particular, you can desing the source so that it emits only one photon
in an interval much larger than the time required for the photon to
Then you can be sure (with high probability) that there is at most one
photon at time traveling in your experimental system.
