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.

Category: Quantum field theory

Quantum field theories for the strong nuclear force and the weak nuclear force have also been developed.

Category: Quantum field theory

Quantum field theory ( QFT ) provides a theoretical framework for constructing quantum mechanical models of systems classically represented by an infinite number of degrees of freedom, that is, fields and ( in a condensed matter context ) many-body systems.

Quantum field theories are used in many contexts, and are especially vital in elementary particle physics, where the particle count / number may change over the course of a reaction.

Quantum field theory frequently makes use of the Lagrangian formalism from classical field theory.

Quantum field theory uses this same Lagrangian procedure to determine the equations of motion for quantum fields.

Quantum electrodynamics ( QED ) is the relativistic quantum field theory of electrodynamics.

Quantum information processing is the most general field that is concerned with quantum information.

* Center for Quantum Computation-The CQC, part of Cambridge University, is a group of researchers studying quantum information, and is a useful portal for those interested in this field.

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 gravity can be treated as an effective field theory.

** Quantum chromodynamics, a theory of the strong interaction ( color force )

Quantum theory tells us that every particle exhibits wave properties.

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

EPR tried to set up a paradox to question the range of true application of Quantum Mechanics: Quantum theory predicts that both values cannot be known for a particle, and yet the EPR thought experiment purports to show that they must all have determinate values.

Finite fields are important in number theory, algebraic geometry, Galois theory, cryptography, coding theory and Quantum error correction.

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 ).

Physicist Lee Smolin writes in Three Roads to Quantum Gravity that topos theory is " the right form of logic for cosmology " ( page 30 ) and " In its first forms it was called ' intuitionistic logic '" ( page 31 ).

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 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 theory also provides accurate descriptions for many previously unexplained phenomena, such as black body radiation and the stability of the orbitals of electrons in atoms.

Quantum information science is an area of study based on the idea that information science depends on quantum effects in physics.

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.

For instance, James G. Gilson has constructed a " Quantum Theory of Gravity " based loosely on Dirac's large number hypothesis.

On hearing of the fall of Edessa to the Turks, he had, in December 1145, addressed the bull Quantum praedecessores to Louis VII of France, calling on him to take part in another crusade.

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 computers are different from digital computers based on transistors.

Quantum computers only run probabilistic algorithms, so BQP on quantum computers is the counterpart of BPP (" bounded error, probabilistic, polynomial time ") on classical computers.

Quantum field theory on curved ( non-Minkowskian ) backgrounds, while not a full quantum theory of gravity, has shown many promising early results.

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

Currently, much more sophisticated theoretical approaches, based on Quantum Field Theory and Nonequilibrium Green Function Theory are in vogue.
