They're related, but computer science has nothing to do with how electrons interact in different materials. Not that it isn't useful for people to know how the lower level components actually work. For that matter, people building the lower level components will also be more useful knowing how they're used in the abstract level. And similarly, studying QC in the theoretical form can also lead to discovery and understanding of quantum properties. Even if we have no fully-featured quantum computers.
