To pursue research in advanced physics, particularly quantum mechanics, transitioning from a bachelor's degree in electronics and communication to a degree in physics is recommended. While it is possible to enter graduate school in physics without a physics major, it requires significant self-study and high performance on admission tests, making it a challenging path. Engaging in physics-related summer courses or internships can provide valuable experience. The discussion highlights the importance of finding a good mentor and acknowledges the competitive nature of the field. Practical considerations, such as financial stability and societal expectations in India, are also emphasized, suggesting that potential students carefully weigh the implications of changing fields, especially regarding long-term career prospects and personal life decisions.
