    • The basic idea of how to observe the (Formula presented) is as follows: If one photon is registered by the trigger detector (Formula presented) in the reflected output of the polarizing beam splitter (PBS), and the others in arms (Formula presented), (Formula presented), and (Formula presented), then two of those three photons have horizontal polarization, with the third being vertically polarized. For having twice the probability of observing horizontally polarized photons compared to vertically polarized ones, we place a polarization dependent beam splitter (PDBS) in arm (Formula presented) (with transmissions (Formula presented)). The remaining two photons are interfered at a 50-50 beam splitter (BS) and distributed into arms (Formula presented) and (Formula presented) by a second BS
