Quantum optics gained practical importance with the invention of the maser in 1953 and the laser in 1960.

* Quantum oscillator may refer to an optical local oscillator, as well as to a usual model in quantum optics.

Quantum mechanics has since branched out into almost every aspect of 20th century physics and other disciplines, such as quantum chemistry, quantum electronics, quantum optics, and quantum information science.

* Quantum mechanics: In quantum mechanics, which deals with the behavior of very small objects, it is not possible to observe a system without changing the system, and the " observer " must be considered part of the system being observed.

* Quantum computing, which deals on the one hand with the question how and whether one can build a quantum computer and on the other hand, algorithms that harness its power ( see quantum algorithm )

Quantum chromodynamics is the portion of the Standard Model that deals with strong interactions, and QCD vacuum is the vacuum of quantum chromodynamics.

Engines do not typically account for Modern Mechanics ( see Theory of relativity and Quantum mechanics ) because most visualization deals with large bodies moving relatively slowly, but the most complicated engines perform calculations for Modern Mechanics as well as Classical.

Quantum chemistry, a branch of theoretical chemistry, deals with the application of quantum mechanics to questions in chemistry.

Quantum process tomography ( QPT ) deals with identifying an unknown quantum dynamical process.

Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature.

Lectures with the titles ' The Copenhagen Interpretation of Quantum Theory ' and ' Criticisms and Counterproposals to the Copenhagen Interpretation ', that Heisenberg delivered in 1955, are reprinted in the collection Physics and Philosophy.

The books that were influential in the early development of computational quantum chemistry include Linus Pauling and E. Bright Wilson's 1935 Introduction to Quantum Mechanics – with Applications to Chemistry, Eyring, Walter and Kimball's 1944 Quantum Chemistry, Heitler's 1945 Elementary Wave Mechanics – with Applications to Quantum Chemistry, and later Coulson's 1952 textbook Valence, each of which served as primary references for chemists in the decades to follow.

* Relativity and Quantum field theory ( physics ), η ( with two subscripts ) represents the metric tensor of Minkowski space ( flat spacetime ).

Quantum mechanics was developed with the aim of describing atoms and explaining the observed spectral lines in a measurement apparatus.

CESG does not manufacture security equipment, but works with industry to ensure the availability of suitable products and services, while GCHQ itself can fund research into such areas, for example to the Centre for Quantum Computing at Oxford University and the Heilbronn Institute at the University of Bristol.

This has been demonstrated in the famous Lamb-Retherford experiment and was the starting point for the development of the theory of Quantum electrodynamics ( which is able to deal with these vacuum fluctuations and employs the famous Feynman diagrams for approximations using perturbation theory ).

; Quantum mechanics or Particle physics: When a spinless particle ( or even an unpolarized particle with spin ) decays, the resulting decay distribution must be isotropic in the rest frame of the decaying particle regardless of the detailed physics of the decay.

Bernard d ' Espagnat a French theoretical physicist best known for his work on the nature of reality wrote a paper titled The Quantum Theory and Reality according to the paper: " The doctrine that the world is made up of objects whose existence is independent of human consciousness turns out to be in conflict with quantum mechanics and with facts established by experiment.

Quantum dots ( nanoparticles with quantum confinement properties, such as size-tunable light emission ), when used in conjunction with MRI ( magnetic resonance imaging ), can produce exceptional images of tumor sites.

Quantum chemistry, a subfield of physical chemistry especially concerned with the application of quantum mechanics to chemical problems, provides tools to determine how strong and what shape bonds are, how nuclei move, and how light can be absorbed or emitted by a chemical compound.

On 8 November 1760, Clement XIII issued a Papal bull Quantum ornamenti, which approved the request of King Charles III of Spain to invoke the Immaculate Conception as the Patroness of the Spanish Kingdom, along with its eastern and western territories, while also maintaining Saint James the Greater be given a distinguished honor as co-patron.

Quantum mechanics ( QM – also known as quantum physics, or quantum theory ) is a branch of physics dealing with physical phenomena at microscopic scales, where the action is on the order of the Planck constant.
