<human>:  Could you give me a brief explanation of quantum physics?
<bot>: Quantum physics is a branch of physics that studies the behavior of matter and energy at the atomic and subatomic levels. It uses the principles of quantum mechanics to explain phenomena such as the wave-particle duality of matter, the uncertainty principle, and quantum entanglement. In simple terms, quantum physics can be thought of as the study of very small things like atoms, photons, and electrons, and how they interact with one another. At these fine scales, the rules of classical physics no longer apply, and instead we must use quantum mechanics to make sense of the behavior. Thus, quantum physics has enabled us to gain a greater understanding of the incredible and often bizarre nature of the universe.
