Chapter 6 Quantum Computation
... Assuming that NP 6= co−NP , there is a theorem that says that no co-NP problems are contained in NPC. Therefore, problems in the intersection of NP and co-NP , if not in P , are good candidates for inclusion in NPI. In fact, a problem in NP ∩ co−NP that is believed not in P is the FACTORING problem. ...

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.
