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

According to a poll at a Quantum Mechanics workshop in 1997 ,< ref > the Copenhagen interpretation is the most widely-accepted specific interpretation of quantum mechanics, followed by the many-worlds interpretation.

Quantum mechanics under the Copenhagen Interpretation interpreted probability as a physical phenomenon, which is what Jaynes called a Mind Projection Fallacy.

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

Quantum theory and quantum mechanics do not provide single measurement outcomes in a deterministic way.

Quantum mechanics has very accurately demonstrated this hypothesis, and the relation has been shown explicitly for particles as large as molecules.

; 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 mechanics is of a wider scope, as it encompasses classical mechanics as a sub-discipline which applies under certain restricted circumstances.

Quantum mechanics has superseded classical mechanics at the foundational level and is indispensable for the explanation and prediction of processes at molecular and ( sub ) atomic level.

Quantum mechanics is a set of principles describing physical reality at the atomic level of matter ( molecules and atoms ) and the subatomic ( electrons, protons, and even smaller particles ).

Although Schrödinger himself after a year proved the equivalence of his wave-mechanics and Heisenberg's matrix mechanics, the reconciliation of the two approaches and their modern abstraction as motions in Hilbert space is generally attributed to Paul Dirac, who wrote a lucid account in his 1930 classic Principles of Quantum Mechanics.

Quantum field theory has driven the development of more sophisticated formulations of quantum mechanics, of which the one presented here is a simple special case.

Quantum optics deals with the application of quantum mechanics to optical systems.

* Quantum mechanics

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.

* Quantum annealing, a method for finding solutions to combinatorial optimisation problems and ground states of glassy systems using quantum fluctuations

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.

The idea of MWI originated in Everett's Princeton Ph. D. thesis " The Theory of the Universal Wavefunction ", developed under his thesis advisor John Archibald Wheeler, a shorter summary of which was published in 1957 entitled " Relative State Formulation of Quantum Mechanics " ( Wheeler contributed the title " relative state "; Everett originally called his approach the " Correlation Interpretation ", where " correlation " refers to quantum entanglement ).

* Quantum mass manifests itself as a difference between an object ’ s quantum frequency and its wave number.

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

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.

Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales.

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 coherence is an essential difference between classical and quantum theories, and is illustrated by the Einstein-Podolsky-Rosen paradox.

Quantum coherence is not typically evident at macroscopic scales-although an exception to this rule can occur at extremely low temperatures ( i. e. approaching absolute zero ), when quantum behavior can manifest itself on more macroscopic scales ( see macroscopic quantum phenomena, Bose-Einstein condensate, and Quantum machine ).

Quantum brute force is easily defeated by doubling the key length, which has little extra computational cost in ordinary use.

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 ).

The first complete mathematical formulation of this approach is generally credited to John von Neumann's 1932 book Mathematical Foundations of Quantum Mechanics, although Hermann Weyl had already referred to Hilbert spaces ( which he called unitary spaces ) in his 1927 classic paper and book.

* In 1983 Robert Anton Wilson published a non-fiction book called Prometheus Rising ( which was followed by Quantum Psychology )

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 entanglement forms the basis of quantum cryptography, which is used in high-security commercial applications in banking and government.

Quantum electrodynamics ( or " quantum electromagnetism "), which is currently ( in the perturbative regime at least ) the most accurately tested physical theory, < sup >( blog )</ sup > has been successfully merged with the weak nuclear force into the electroweak force and work is currently being done to merge the electroweak and strong force into the electrostrong force.

Quantum mechanics can also provide quantitative insight into ionic and covalent bonding processes by explicitly showing which molecules are energetically favorable to which others, and the magnitudes of the energies involved.

Quantum mechanically, we measure the three-qubit state, which is equivalent to collapsing the quantum state down to a classical distribution ( with the coefficients in the classical state being the squared magnitudes of the coefficients for the quantum state, as described above ), followed by sampling from that distribution.

Quantum information differs from classical information in several respects, among which we note the following:

Quantum teleportation, or entanglement-assisted teleportation, is a process by which a qubit ( the basic unit of quantum information ) can be transmitted exactly ( in principle ) from one location to another, without the qubit being transmitted through the intervening space.

Quantum gravity ( QG ) is the field of theoretical physics which attempts to develop scientific models that unify quantum mechanics ( describing three of the four known fundamental interactions ) with general relativity ( describing the fourth, gravity ).

* Quantum field theory, a generic type of relativistic quantum theory, which includes:

* Quantum Zeno effect, an effect in quantum mechanics which disallows certain conditions in the decaying of a quantum state

In the Quantum Leap episode " The Great Spontini ", Scott Bakula's character, Dr. Sam Beckett, leaps into an amateur magician in 1974 who aspires to appear on Bill Bixby's The Magician ; however, owing to his partial amnesia, Dr. Beckett, at first, can only recall Bixby's connection with The Incredible Hulk, which had not been made at that time.
