Quantum mechanics, the branch of physics that deals with the behavior of matter and energy at the smallest scales, has led to the development of numerous groundbreaking inventions. One of the most notable is the transistor, a fundamental component of modern electronics that powers everything from computers to smartphones. Quantum mechanics also underpins the operation of semiconductors used in these devices, allowing for faster processing and miniaturization. The laser, another quantum-based invention, is used in countless applications, from communication systems (such as fiber optics) to medical treatments and entertainment.
