Locality of superposition principle is dictated by detection processes

Both classical and quantum physics thrive on the superposition principle (SP), yet the first one takes it as a local effect and the second one assumes it as a non-local phenomenon. We take SP as a tool to bridge the two worlds into one causal frame work by introducing extended interpretations on each one of the mathematical symbols and operators representing the photo detection equation for the case of various two-beam interferometer experiments. The experiments dramatize classical locality. The locality argument arises because the recorded energy re-distribution due to superposition of fields is due to real energy exchange through field-dipole interaction, and not due to field-field interaction. EM fields do not interact with each other in absence of material dipoles. All QM interactions are mediated through amplitude-amplitude stimulation, which is at the root of superposition principle. The detector dipoles attempt to respond to the sum of all the locally superposed EM fields, if allowed quantum mechanically, actualizing the principle of superposition. The energy exchange by the dipoles follow the standard prescription, ensemble average of the square modulus of all the superposed
