I have been reading about physicists that study things like computational neuroscience/AI and quantum computing. It is my understanding that these subjects are very closely linked and form a relatively new and open area of science research. I also have the impression that a physics degree is the most broad and thus best for entering this sort of interdisciplinary and new research. Is this correct? If I pursue a PhD in theoretical physics, with the goal of studying in this area, is there anything specific that I should do to improve my ability to land postdocs/faculty positions/etc? Thanks!
