Quantum information science. Quantum information science is an area of study based on the idea that information science depends on quantum effects in physics.
It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done with quantum information. The term quantum information theory is sometimes used, but it fails to encompass experimental research in the area. Subfields include: See also[edit] Quantum chemistry. Quantum chemistry is a branch of chemistry whose primary focus is the application of quantum mechanics in physical models and experiments of chemical systems.
It involves heavy interplay of experimental and theoretical methods: In these ways, quantum chemists investigate chemical phenomena. Quantum optics. Quantum optics is a field of research in physics, dealing with the application of quantum mechanics to phenomena involving light and its interactions with matter.It basically deals with the interaction of light with matter in a microscopic point of view.
Both semiclassical and fully quantum mechanical pictures are used to understand the quantum optical phenomena. History of quantum optics[edit] Light propagating in a vacuum has its energy and momentum quantized according to an integer number of particles known as photons. Quantum optics studies the nature and effects of light as quantized photons.
The first major development leading to that understanding was the correct modeling of the blackbody radiation spectrum by Max Planck in 1899 under the hypothesis of light being emitted in discrete units of energy.
