   Quantum Electrodynamics (QED)
   While classical electromagnetism excels at describing macroscopic phenomena, the interaction of light and matter at the atomic scale requires a quantum mechanical description. Quantum Electrodynamics (QED), developed primarily by Richard Feynman, Julian Schwinger, and Sin-Itiro Tomonaga, is the quantum field theory of electromagnetism.
   In QED, the electromagnetic force is mediated by the exchange of virtual photons, the quantu…
