quantum mechanics is a fundamental theory in physics that describes the behaviour of matter and light on the atomic and subatomic scale. It is based on the concept of wave-particle duality, which means that elementary particles can exhibit both particle-like and wave-like properties. quantum mechanics also incorporates the uncertainty principle, which states that there are limits to how precisely one can measure certain physical quantities, such as position and momentum, of a system. quantum mechanics is the foundation of many branches of physics, such as quantum chemistry, quantum field theory, quantum technology, and quantum information science.
