Say, what is the square of a photon, anyway?
One way to square photons is to make them pass through a sufficiently
small square hole in an opaque plate. The squared photons will undergo
a diffraction distortion, so whether the resulting value is 1 or 0
(photons visible or not) will depend on the angle between the hole and
your observation apparatus.
The basic technique has already been studied. You can see a simulation
of the results here:
