Wikipedia
Quantum electrodynamics
In particle physics, quantum electrodynamics (QED) is the relativistic quantum field theory of electrodynamics. In essence, it describes how light and matter interact and is the first theory where full agreement between quantum mechanics and special relativity is achieved. QED mathematically describes all phenomena involving electrically charged particles interacting by means of exchange of photons and represents the quantum counterpart of classical electromagnetism giving a complete account of matter and light interaction. In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum. Richard Feynman called it "the jewel of physics" for its extremely accurate predictions of quantities like the anomalous magnetic moment of the electron and the Lamb shift of the energy levels of hydrogen.: Ch1

quantum electrodynamics
Quantum electrodynamics (QED) is a quantum field theory that describes how light and matter interact. It can be considered as the quantum version of classical electrodynamics. The theory combines key principles of both quantum mechanics and special relativity to describe the interactions between electrically charged particles, such as electrons and protons, via exchange of photons, which are the particles of light. It is one of the most precise and successful theories in physics, with predictions that have been extensively tested and confirmed through experiments.
