If you want to do experiments, then most core physics courses should do the trick. There are many proposed implementations using light (i.e. optics), ion traps (EM), superconductors, etc. Of course a quantum mechanics course is useful too.

If you want to only do theory though, you don’t really need to study much physics at all. Computer science and information theory is far more relevant.
