Photon as a quantum object The existence of indivisible photons
is to be shown experimentally. The light source emits pairs of
photons (see basic principles). One of the photons is absorbed
in the trigger detector and the other photon of the pair is now
known to be present. This photon is incident on an optical beam
splitter, as shown in figure 1. The analysis of observation can
be done in different ways: |Count rates continous| |Second order
correlation (advanced)| Figure 1: Single photons, heralded by
trigger detector, are incident on beam splitter Approach 1:
Single events A bright light beam incident on a beam splitter
would be divided into two separate, continuous beams with half
intensity (or a different, but fixed division ratio according to
the reflectivity of the splitting surface). In our quantum
experiment, you can send single photons to the beam splitter and
check for the detectors. The multimedia experiment requires the
