Electron-Positron Scattering
... To associate each diagram with an actual formula for the corresponding amplitude, we use what are called the Feynman rules. The rules tell us to write a brief formula for each part of a diagram (each external line, each internal line, and each vertex), then multiply these expressions together to obt ...

... When you change the electrical field vector of one, the other one will change to match it exactly. If you move it 10 degrees, the other photon will move its field vector 10 degrees. So you have this "communication" going on between photons even though they are separated by a very large distance. And ...

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.
