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 mechanically it is not unreasonable to assume that the momenta of the electrons and nuclei in a molecule are comparable in magnitude ( recall that the corresponding operators do not contain mass and think of the molecule as a box containing the electrons and nuclei and see particle in a box ).

Quantum mechanically, this corresponds to mixing orbitals that differ in the l and m quantum numbers, such as the s ( l = 0 ) and p ( l = 1 ) atomic orbitals.

Quantum mechanically, the energy of the-th level of a harmonic oscillator is given by:

Quantum mechanically, the situation is even simpler ( conceptually ).

Quantum mechanically, this is described as a resonance between the non-bonded state | D, A > and the dative state | D < sup >+</ sup >... A < sup >-</ sup >>.

Quantum mechanically, the CARS process can be understood as follows.

Quantum mechanically, the chiral current is not conserved: Jackiw discovered this due to the non-vanishing of a triangle diagram.

" In an article in the Guardian titled Quantum weirdness: What we call ' reality ' is just a state of mind d ' Espagnat wrote that:

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

* Arthur Wightman: Should we believe in Quantum Field Theory ?.

Quantum information specifies the complete quantum state vector ( or equivalently, wavefunction ) of a system, whereas classical information, roughly speaking, only picks out a definite ( pure ) quantum state if we are already given a prespecified set of distinguishable ( orthogonal ) quantum states to choose from ; such a set forms a basis for the vector space of all the possible pure quantum states ( see pure state ).

They say: ' Quantum electrodynamics is a good theory and we do not have to worry about it any more.

At that time we will substitute in the " chiral " or " Weyl " representation as used in the popular graduate textbook An Introduction to Quantum Field Theory by Michael E. Peskin and Daniel V. Schroeder.

" Fredkin answers his own question, " If so, we have to rethink particle disintegrations, inelastic collisions and Quantum Mechanics to better understand what is happening to the information.

Like Sam Beckett in Quantum Leap we will strive to " put right what once went wrong ”… and then just like him we will poof out of existence.

As with most papal bulls, it had no specific title, and has come to be known by its opening words ; in Latin the first sentence read " Quantum praedecessores nostri Romani pontifices pro liberatione Orientalis Ecclesiae laboraverunt, antiquorum relatione didicimus, et in gestis eorum scriptum reperimus " – in English, " How much our predecessors the Roman pontiffs did labour for the deliverance of the oriental church, we have learned from the accounts of the ancients and have found it written in their acts.

According to Dirac: ” Quantum electrodynamics is the domain of physics that we know most about, and presumably it will have to be put in order before we can hope to make any fundamental progress with other field theories, although these will continue to develop on the experimental basis .”

* Quantum efficiency, a measure of sensitivity of a photosensitive device

Quantum meruit is the measure of damages where an express contract is mutually modified by the implied agreement of the parties, or not completed.

An equivalent ( and more intuitive ) operational definition of the quantum conditional entropy ( as a measure of the quantum communication cost or surplus when performing quantum state merging ) was given by Michał Horodecki, Jonathan Oppenheim, and Andreas Winter in their paper " Quantum Information can be negative ".

In his article entitled " Criticism and Counterproposals to the Copenhagen Interpretation of Quantum Theory ," countering the view of Alexandrov that ( in Heisenberg's paraphrase ) " the wave function in configuration space characterizes the objective state of the electron.

* Quantum chemistry and solid state physics software supporting several methods.

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 state

Quantum computers share theoretical similarities with non-deterministic and probabilistic computers, like the ability to be in more than one state simultaneously.

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

This is a derivation of the Quantum Hall state of matter.

Quantum indeterminacy means that these states cannot in general be measured without disturbing the original state ( see No cloning theorem ).

Quantum indeterminacy is the assertion that the state of a system does not determine a unique collection of values for all its measurable properties.

* Quantum state intentionally altered in molecule

* Quantum state in macroscopic object

Quantum mechanics is also not " local ", essentially because the state of a system is described by the Hilbert vector, which includes the value at every site,.

Quantum information could thus be expressed by providing ( 1 ) a choice of a basis such that the actual quantum state is equal to one of the basis vectors, together with ( 2 ) the classical information specifying which of these basis vectors is the actual one.

* Quantum state, in physics, the state of a quantum mechanical system given by a vector in the underlying Hilbert space

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

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

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.

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

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.

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 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.

* 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 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:
