  • Quantum - Wikipedia
    In physics, a quantum (pl : quanta) is the minimum amount of any physical entity (physical property) involved in an interaction The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization" [1]
  • Quantum | Definition Facts | Britannica
    Quantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property Light, for example, appearing in some respects as a continuous electromagnetic wave, on the submicroscopic level is emitted and absorbed in discrete amounts, or quanta
  • Demystifying Quantum: It’s Here, There and Everywhere
    Quantum, often called quantum mechanics, deals with the granular and fuzzy nature of the universe and the physical behavior of its smallest particles The idea of physical granularity is like your TV image
  • What Is Quantum Physics? - Caltech Science Exchange
    Quantum physics is the study of matter and energy at the most fundamental level It aims to uncover the properties and behaviors of the very building blocks of nature While many quantum experiments examine very small objects, such as electrons and photons, quantum phenomena are all around us, acting on every scale
  • What is quantum theory? | Definition from TechTarget
    Quantum theory, or quantum mechanics, is the theoretical basis of modern physics that explains the nature and behavior of matter and energy on the subatomic level Quantum theory deals with subatomic phenomena while the theory of relativity deals with the macroscopic world
  • DOE Explains. . . Quantum Mechanics | Department of Energy
    Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy) Physicists call this the “wave-particle duality ”
  • Quantum - definition of quantum by The Free Dictionary
    A unit of energy, especially electromagnetic energy, that is the smallest physical quantity that can exist on its own A quantum acts both like a particle and like an energy wave Photons are examples of quanta
  • Quantum mechanics - Wikipedia
    Quantum mechanics allows the calculation of properties and behaviour of physical systems It is typically applied to microscopic systems: molecules, atoms and subatomic particles
  • Quantum mechanics | Definition, Development, Equations | Britannica
    Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons
  • What is quantum in physics and computing? - TechTarget
    A quantum, the singular form of quanta, is the smallest discrete unit of any physical entity For example, a quantum of light is a photon, and a quantum of electricity is an electron Quantum comes from Latin, meaning an amount or how much If something is quantifiable, it can be measured What is quantum in physics?
