The understanding of the interaction between light and matter following these developments was crucial for the development of quantum mechanics as a whole. However, the subfields of quantum mechanics dealing with matter-light interaction were principally regarded as research into matter rather than into light; hence one rather spoke of atom physics and quantum electronics in The latter are of much interest in quantum information theorya subject which partly emerged from quantum optics, partly from theoretical computer science.
Other remarkable results are the demonstration of quantum entanglementquantum teleportationand quantum logic gates. Several Nobel prizes have been awarded for work in quantum optics.
Raman spectroscopy were found, and mechanical forces of light on matter were studied. Applications for solid state research e.
Topics classified under the term of quantum optics, especially as applied to engineering and technological innovation, often go under the modern term photonics. Development of short and ultrashort laser pulses—created by Q switching and modelocking techniques—opened the way to the study of what became known as ultrafast processes.
The first major development leading to that understanding was the correct modeling of the blackbody radiation spectrum by Max Planck in under the hypothesis of light being emitted in discrete units of energy.
Niels Bohr showed that the hypothesis of optical radiation being quantized corresponded to his theory of the quantized energy levels of atomsand the spectrum of discharge emission from hydrogen in particular.
InKimble et al. The latter led to levitating and positioning clouds of atoms or even small biological samples in an optical trap or optical tweezers by laser beam.
Glauberand Leonard Mandel applied quantum theory to the electromagnetic field in the s and s to gain a more detailed understanding of photodetection and the statistics of light see degree of coherence. Quantum optics studies the nature and effects of light as quantized photons.
The photoelectric effect was further evidence of this quantization as explained by Einstein in a paper, a discovery for which he was to be awarded the Nobel Prize in As laser science needed good theoretical foundations, and also because research into these soon proved very fruitful, interest in quantum optics rose.
This led to the introduction of the coherent state as a concept which addressed variations between laser light, thermal light, exotic squeezed statesetc.
History[ edit ] Light propagating in a vacuum has its energy and momentum quantized according to an integer number of particles known as photons. This, along with Doppler coolingwas the crucial technology needed to achieve the celebrated Bose—Einstein condensation.Nonintegrability and quantum fluctuations in a quantum optical model.

quantum optical implementation of quantum information processing and classical simulation of many-body physics from quantum information perspective. The law of cause and effect is a central tenet of the scientific method.
Until recently, it was always assumed that any change was produced by a cause. Some say that some quantum mechanical events are not caused. The fact is that there are causal.
