Quantization is one of the foundations of the much broader physics of quantum mechanics. Quantization of energy and its influence on how energy and matter interact (quantum electrodynamics) is part of the fundamental framework for understanding and describing nature.

May 31, 2025 · 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.

Apr 10, 2024 · 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 …

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.

Jul 15, 2025 · You may not have realized it yet, but the United Nations has declared 2025 the International Year of Quantum Science and Technology.

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).

Feb 27, 2025 · Quantum technology uses the nature of subatomic particles to perform calculations instead of electrical signals like classical computing. Quantum computers use quantum bits or qubits instead of binary bits.

May 27, 2024 · Quantum mechanics stands as one of the most intriguing and fundamental branches of physics, delving into the behavior of particles at the atomic and subatomic levels. …

So, what is quantum? In a more general sense, the word “ quantum” can refer to the smallest possible amount of something. The field of quantum mechanics deals with the most fundamental bits of matter, energy and light and the ways they interact with each other to make up the world.

What is Quantum? Everything physical around us is made of matter, from the air we breathe to the water we drink – even our own bodies are made of matter. In its smallest measurable form, matter is made up of atoms.
