Quantum Theory is a branch of physics that focuses on studying the behavior and precise properties of materials on the atomic and molecular scale. It includes a wide range of physical phenomena and phenomena that depend on quantum concepts such as independent energy (energy levels) and existing waves (waves). Applications of quantum theory include several areas, such as:

• Atomic and molecular physics: understanding the behavior and interactions at the level of atoms and molecules, including the electronic structures and chemical properties of materials.
• Nuclear physics: the study of nuclear reactions, properties, and structures at the level of the atomic nucleus, including nuclear decay and collisions.
• High-energy particle physics: the study of fundamental particles and the high-energy interactions that occur at the level of small particles such as protons and neutrons.
• Chemical Physics: Understanding chemical reactions and molecular bonds using quantum concepts.
• Quantum computing: The use of quantum theory to solve complex computational problems that exceed the conventional capacity of classical computing.

Objectives of studying quantum theory and its applications:

• Understand and explain physical phenomena at the fine scale of atoms and molecules.
