What's GTRI's relation to Georgia Tech?

As an undergraduate, what does GTRI do for me? Would I be able to join GTRI research groups that I find interesting, like the Quantum Information Systems group?

(Also: does GATech offer any other resources for learning/researching quantum computing?)

Students do get research positions at GTRI. Its easy to walk from campus to GTRI.
There is a professor in chemistry who also studies quantum computing:
