# Quantum Physics vs. Quantum Mechanics: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 27, 2024

Quantum physics is the broad field studying the behavior of matter and energy at quantum scales, while quantum mechanics is the theoretical framework within this field.

## Key Differences

Quantum physics encompasses the overall study of the smallest particles of matter and their interactions at the subatomic level. Quantum mechanics, a subset of quantum physics, is a fundamental theory that provides a mathematical framework to describe these phenomena.
