... A question that has generated much discussion is where the extra power of quantum computers comes from. There are a number of di erences between quantum and classical computers, and most appear to be required for the extra power. In particular, quantum interference is needed; one high-level way to d ...

Destructive quantum interference in spin tunneling problems
... (n is some integer) [10]. Again one can study the tunneling between two configurations that only differ by φl → φl + π (i.e. A ↔ B) for each spin on the loop. The relevant phase between (+)- and (−)- paths will be iπ(4n + 2)s, and for half-odd-integer s, destructive interference again occurs. The ab ...

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.
