Quantum Electrodynamics

Quantum Electrodynamics

Quantum Electrodynamics (QED) is the quantum field theory describing the interaction between charged particles and electromagnetic fields. It explains how electrons and photons interact through the exchange of virtual particles. QED is one of the most precise and successful theories in physics, producing predictions confirmed to extraordinary accuracy. It accounts for phenomena such as electron scattering, atomic radiation, and electromagnetic forces. QED introduced key concepts such as renormalization and gauge symmetry. Its theoretical framework laid the foundation for other quantum field theories. Quantum electrodynamics plays a critical role in particle physics, atomic physics, and precision measurements. It represents a major achievement in the understanding of fundamental interactions.
