This is a bit of a nitpick, but when you say Computer Science I think you mean Software Engineering and/or Computer Engineering. These are very different fields, and Computer Science is by-and-large agnostic of any actual physics.
As an anecdote: my Computer Science PhD dissertation contained all of about 12 lines of pseudocode, and these are only to provide a more direct description of an idea than I was able to provide with several paragraphs of prose. Hardware / architecture / physics is entirely irrelevant to it -- while any implementation of the ideas therein should be aware of hardware / physics / etc., we are solidly entering the realm of engineering at that point.
