An M.Tech degree may not provide the same depth of knowledge in quantum mechanics as a dedicated major in the field. While an M.Tech can offer a foundational understanding, it typically focuses on practical applications rather than the theoretical depth found in specialized quantum mechanics programs. The discussion emphasizes that the extent of knowledge gained largely depends on the resources and textbooks used for study. A bachelor's degree may allow for basic calculations, such as those involving the Schrödinger equation, but advanced topics like quantum field theory (QFT) require additional years of study. Ultimately, quantum mechanics is viewed as a tool in research rather than a standalone major, highlighting the importance of targeted learning for a comprehensive understanding of the subject.
