Developing Causal Interpretations For High And Low Level Light Used In Quantum Sensing

We present observational and causality arguments to underscore that a better model for light is a "hybrid photon" wave packet. At the moment of quantum transitions, the electromagnetic energy is embedded in the transient quantum, h nu. But, it immediately evolves into a diffractively spreading classical, quasi-exponential, EM wave packet. This hybrid photon accommodates both quantum and classical optics. The quantum formalism has demonstrated staggering successes in modeling the micro world of atoms. The Huygens-Fresnel diffraction integral and Maxwell's wave equation are also enjoying continued successes since early 1800's. In this paper, using the model of hybrid photon, we underscore that the photoelectron counting statistics should vary depending upon the relative phases, spacing and amplitudes of the superposed wave packets (hybrid photons) as they simultaneously arrive and stimulate the quantum mechanical dipole complexes on the surface of the photo detectors.
