Quantum Mechanics and Quantum Physics are often used interchangeably, as they both refer to the same branch of physics that deals with the behavior of matter and energy at the smallest scales. However, there is a subtle difference between the two terms.
Sep 12, 2022 · In quantum mechanics, the state of a physical system is represented by a wave function. In Born’s interpretation, the square of the particle’s wave function represents the probability density of finding the particle around a specific location in space.
Quantum physics is the branch of physics that deals with small objects and the quantization of various entities, including energy and angular momentum. Just as with classical physics, quantum physics has several subfields, such as mechanics and the study of electromagnetic forces.
