Introduction
Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at and below the scale of atoms. It is the foundation of all quantum physics, including quantum chemistry, quantum field theory, quantum technology, and quantum information theory. It is different from classical physics, as at the scale of atoms and electrons, many of the equations of classical mechanics cease to be useful, and objects exist in a haze of probability.
