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Quantum mechanics has superseded classical mechanics at the foundational level and is indispensable for the explanation and prediction of processes at molecular and ( sub ) atomic level.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: 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 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 states of a particle and an antiparticle can be interchanged by applying the charge conjugation ( C ), parity ( P ), and time reversal ( T ) operators.

* Quantum superpositions can be described as vector sums of the constituent states.

Quantum processes can also produce EMR, such as when atomic nuclei undergo gamma decay, and processes such as neutral pion decay.

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.

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 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 information, and changes in quantum information, can be quantitatively measured by using an analogue of Shannon entropy, called the von Neumann entropy.

* Quantum information can be negative

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 can be treated as an effective field theory.

Quantum systems can become entangled through various types of interactions ( see section on methods below ).

* Hyperdrives allow for faster-than-light travel, but at a rate slow enough ( 1 light year per 3 days, ~ 122c ) to keep the galaxy vast and unknown ; the new Quantum II Hyperdrive, developed by the Puppeteers but not yet released to humans, can cross a light year in just 1. 25 minutes (~ 425, 000c ).

The theory of the weak interaction can be called Quantum Flavordynamics ( QFD ), in analogy with the terms QCD and QED, but in practice the term is rarely used because the weak force is best understood in terms of electro-weak theory ( EWT ).

This trend can be seen in Syriana, the Bourne film series and the more recent James Bond films Casino Royale ( 2006 ) and Quantum of Solace ( 2008 ).

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.

Sam refuses to allow this, and before he can be stopped, he enters the Quantum Leap accelerator, disappearing into time.

Quantum logic can be regarded as a kind of propositional logic suitable for understanding the apparent anomalies regarding quantum measurement, most notably those concerning composition of measurement operations of complementary variables.

Quantum mechanically, this can be described as an excitation to a higher energy state and then a return to a lower energy state accompanied by the emission of a photon.

Quantum mechanics is different, because the numbers can be positive or negative.

Quantum effects that are consequences only of quantum fluctuations, not of subtleties of measurement incompatibility, can alternatively be models of classical continuous random fields.
