... Quantum information theory is the combination of quantum mechanics and information theory. The profit is on both sides: quantum mechanics gains valuable aspects concerning the physical interpretation of the theory, and information theory gains enhanced capabilities of information processing and comm ...

... The science of physics seeks to ask, and find precise answers to, basic questions about why nature is as it is. Historically, the fundamental principles of physics have been concerned with questions such as “what are things made of?” and “why do things move as they do?” In his Principia, Newton gave ...

If we are not careful to spell them out, confusion can and will occur when we try to compare descriptions of the world that come out of different theories. In this book we shall be concerned with two very basic ways in which theories may differ. The ®rst is i ...

The SPM images are obtained by scanning a charged tip above the surface of the quantum dot and recording the conductance through the quantum dot in the Coulomb blockade regime as a function of tip position. The lowest energy level in the dot is shifted by the charged SPM tip. This creates a ring of ...

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.
