Quantum physics can be a specialization, but it often leads to applied physics roles. Key job opportunities for quantum physicists include fields like solid-state physics, lasers, and semiconductor-optoelectronics, particularly in solar cell technology utilizing Quantum Wells for enhanced efficiency. Specializations can also extend to areas like quantum optics. However, interests in cosmology, such as black holes, are more aligned with astrophysics and relativity rather than quantum physics itself. For those pursuing careers, academia is a common path, especially for research-focused roles. Understanding the distinctions between quantum physics and related fields is essential for aligning educational pursuits with career goals.
