Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
The idea of quantum field theory began in the late 1920s with British physicist Paul Dirac, when he attempted to quantize the energy of the electromagnetic field; just as in quantum mechanics the energy of an electron in the hydrogen atom was quantized. Quantization is a procedure for constructing a quantum theory starting from a classical theory.
Quantum mechanics, a major field of physics; Old quantum theory, predating modern quantum mechanics; Quantum field theory, an area of quantum mechanics that includes: Quantum electrodynamics; Quantum chromodynamics; Electroweak interaction; Quantum gravity, a field of theoretical physics; Quantum optics; Quantum chemistry; Quantum information
Relativistic quantum physics and quantum field theory. The one-particle Schrödinger equation described above is valid essentially in the nonrelativistic domain. For ...
Quantum physics is a branch of modern physics in which energy and matter are described at their most fundamental level, that of energy quanta, elementary particles, and quantum fields. Quantum physics encompasses any discipline concerned with systems that exhibit notable quantum-mechanical effects, where waves have properties of particles, and ...
Quantum electrodynamics describes a quantum theory of electrons, positrons, and the electromagnetic field, and served as a model for subsequent quantum field theories. [41] [42] [64] Feynman diagram of gluon radiation in quantum chromodynamics. The theory of quantum chromodynamics was formulated beginning in the
