Quantum Electrodynamics

Quantum electrodynamics (QED), a cornerstone of modern physics, investigates the quantum interactions of light and matter. This theory extends the classical Maxwell equations by incorporating quantum mechanics, dealing with the exchange of photons and charged particles. In exploring QED, one examines phenomena such as particle-antiparticle creation and annihilation, and the fundamental aspects of force mediation via virtual photons. This deeper insight not only enriches the theoretical framework of particle physics but also drives advancements in fields like quantum computing and nanotechnology.
