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.
For decades, quantum imaging has promised sharper images and greater light sensitivity than classical methods by exploiting the unique properties of quantum light, such as photon entanglement. But the ...

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.
Quantum physics is the science that explores the deepest layers of reality. It investigates how nature behaves at the smallest scales imaginable—inside atoms, within the fabric of light, and among the invisible particles that make up everything in the universe.
Quantum physics is the study of extremely small atomic particles. Quantum science aims to better understand the world around us and apply quantum theories to real-world technology solutions.
Quantum physics describes the universe at its smallest and most fundamental scales — think atoms and molecules; light and energy. Things at these scales behave very differently from everyday objects we’re familiar with. One of the most important differences involves a concept called superposition.
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.
