Quantum computing is a very niche field and it’s relatively new, therefore it’s very research heavy.
Not many schools allow you to do QC as an undergrad. The University of Maryland, which is one of the leaders in QC research, is one of the few places that lets you do a minor alongside a CS or CE degree.
Unfortunately, UMD will not be affordable for you as they won’t provide any aid. But see if there are other schools that offer a similar option.
