<human>:  Can you explain quantum physics?
<bot>: Quantum physics is a branch of physics that deals with particles and energy at the atomic and subatomic level. It uses equations and theories, such as quantum mechanics, to explain how different particles interact with each other, and how they produce and transmit energy. Quantum physics has been used to explain phenomena such as superconductivity, quantum entanglement, and quantum computing. Its applications are often seen in chemistry, materials science, and computing.
