hey abdul!

quantum physics is the study of subtaomic particles . many students gets attracted by this subject .

firstly i want to say that you are not going to get a particular course in quantum physics at any level . i tell you why ! in your UG you will have to study whole physics which cover whole syllabus ,from light to mechanics .in last year you will face quantum mechanics but just as a intro.

even in msc you will have to study other fields of physics with quantum physics .

however you can do your phd solely in quantum physics so you have to learn a lot before reaching there

so for startup enroll in a good college for your undergraduation
