Quantum optics

Quantum optics, historical and Quantum Electronics, priority can be explained by such optical phenomena not related to the wave nature of electromagnetic radiation (among light), but only from the particle properties ( addresses as part of the field of optics, for example, the photoelectric effect, Compton effect, lasers, masers ).

From quantum hypothesis suggests that light can not be recorded only in the conventional sense but also as an electromagnetic wave as a particle. These particles are called photons. A single photon case has an energy of hf, with Planck 's constant h and the frequency f

Experiments in quantum optics

Experiments in quantum optics investigate the interaction between light and matter.

As a nearly ideal light source for experiments, the laser has here been found, as this is extremely monochromatic and coherent.

Special attention was given to the quantum optics also from the 1990s in connection with experiments on quantum physics and quantum computers. Here are the Nobel Prize in Physics in 2012, Serge Haroche and David Wineland, proved the validity of the quantum mechanical foundations ( Linear Superponierbarkeit quantum mechanical states, as well as " state projection " as a result of quantum measurements) even when ( zerstörungsfreien! ) measurements on single objects.
