Definitions for quantum electrodynamics
This page provides all possible meanings and translations of the word quantum electrodynamics
quantum electrodynamics, QED(noun)
a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
the study of the interaction of electromagnetic radiation with electrically charged matter within the framework of relativity and quantum mechanics
In particle physics, quantum electrodynamics 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. One of the founding fathers of QED, Richard Feynman, has 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. In technical terms, QED can be described as a perturbation theory of the electromagnetic quantum vacuum.
