If I understand correctly, then under "fundamental science of physics" is understood here some of its only theoretical component? Otherwise, experimental physicists had the most direct influence on the invention of computing systems. And who then invented the transistor and received a Nobel Prize for it?
It's more difficult with the influence of theorists. Here we can refer to the fact that purely theoretical predictions in the field of quantum mechanics made it possible to make experimental discoveries (the same transistor, laser, which is used to record information). But to be frankly honest, I will say: in the future, the emergence of quantum computers will be largely the merit of theoreticians rather than experimentalists.
Fundamental science such as physics contributed in part.
It should be understood that the fundamental sciences are not in themselves responsible for technological progress. There are general ideas about the nature of matter, but there are specific ideas about how to use these concepts in everyday life.
Of course, without understanding the conductors, a computer would not work.
