Main Question or Discussion Point

the amplitude of a photon gets divided when it goes through a double slit or through a mach-zender (http://en.wikipedia.org/wiki/Mach%E2%80%93Zehnder_interferometer

what is amplitude of a photon? is it simply related to probability or is it, in any way, to the EM fields?

what gets divided?..when a photon passes through the double slit

we know that the photon is the smallest quanta of energy and cannot be divided

A single photon doesn't get divided. In the double slit experiment it will hit the screen in one spot. Quantum theory gives us the distribution of spots when many photons are used (even one at a time) - diffraction pattern.
