Photons interact with atoms, molecules and other particles of metals and air particles in space or environment, out of which the phenomenon of scattering, absorption, polarization, coupling, propagation, creation and annihilation takes place. Transportation photons and particles takes place in temporal-spatial domains. Boltzmann coupled with Maxwell's equation can thus provide exact solution of wave propagation and quantum fields operators. Also, Schrödinger equation can provide solution to photon fields. Skin effect is dominant in photonic devices, and nonlinear phenomenon also gets introduced at optical spectrum. The solution of electromagnetic wave propagation and fields quantum is different from classical microwave regime. In this chapter, mathematical modeling of quantum fields generation, interaction and propagation has been developed and analyzed. The Dirac equation has been used to determine quantum wave fields. Human eyes have retinas with 5 million of cones of photonic wavelength in central part and 126 million rods in peripheral part to receive photons. They form vision by capturing any image from the real world. They are also known as photo receptors. In brief, light-matter interaction in retinal part takes place, conversion of phonic signal into electrical impulses takes place, now these electrical pulses get accumulated and travel through optical nerves and carry composite signal to brain, which further gets converted into pixels and thus image is formed. Light scattering and propagation solution is provided by Drude's model. Quantum entanglement is another important phenomenon to be used for quantum communication. This is also used for secure quantum communications.
