- 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
- 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
- Quantum mechanics: Definitions, axioms, and key concepts of quantum . . .
Quantum mechanics, or quantum physics, is the body of scientific laws that describe the wacky behavior of photons, electrons and the other subatomic particles that make up the universe
- 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
- Quantum Technology Monitor 2025 | McKinsey
Quantum technology encompasses three subfields: Quantum computing is a new computing paradigm that capitalizes on the laws of quantum mechanics to provide significant performance improvement for certain applications, and to enable new territories of computing beyond existing classical computing
- Quantum physics - Latest research and news - Nature
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
- 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 ”
