No, particle physics and quantum physics are not the same, although they are closely related fields within the broader domain of physics.
Particle physics is a branch of physics that studies the fundamental constituents of matter and radiation, and the interactions between them. It focuses on building a theoretical framework that describes particles such as quarks, leptons, bosons, and their interactions through fundamental forces like electromagnetism, the strong nuclear force, and the weak nuclear force.
On the other hand, quantum physics (or quantum mechanics) is the foundational theory that describes the physical properties of nature at the scale of atoms and subatomic particles. It provides the mathematical framework to understand how these particles behave, including phenomena such as superposition, entanglement, and wave-particle duality.
In summary, while particle physics specifically focuses on the particles and their interactions, quantum physics provides the underlying principles and mathematics that govern how all quantum systems behave, including those studied in particle physics.
