... field-strength is the square-root of a joule per cubic meter. A joule is a unit of energy and a meter is a unit of length, but a square-root of a joule is not a unit of anything tangible. There is no way we can imagine measuring directly the square-root of a joule. The unit of electric field-strengt ...

However, for our multiparty quantum protocols we will first need a new two-party quantum protocol for coin flipping with penalty for cheating. In this problem, players can be heavily penalized for cheating, which will allow ...

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.
