Quantum physics is the study of matter and energy at the most fundamental level. It investigates how nature behaves at the smallest scales. In physics, a quantum (pl.:

Quantum physics describes the universe at its smallest and most fundamental scales think atoms and molecules; Quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. Quantum physics is the science that explores the deepest layers of reality.
It aims to uncover the properties and behaviors of the very building.
Quantum, in physics, discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property.
