In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents.
Quantum is a discrete unit of energy, charge, angular momentum or other physical property. Learn how quantum phenomena apply to light, matter, mechanics and scattering, and see examples and related topics.

Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms.: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science.
Learn what quantum physics is, how it studies matter and energy at the fundamental level, and what phenomena and discoveries it reveals. Explore the origins, principles, mathematics, and observations of quantum science, and how it impacts our understanding of the world.
May 20, 2024 · Learn about the science of quantum mechanics, which deals with the behaviour of matter and light on the atomic and subatomic scale. Explore the historical basis, basic concepts, and unresolved problems of this branch of physics.
Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta.
t. e. Quantum mechanics is the study of matter and its interactions with energy on the scale of atomic and subatomic particles. By contrast, classical physics explains matter and energy only on a scale familiar to human experience, including the behavior of astronomical bodies such as the moon.
