I have a bachelor's in CS with a math focus (wound up 1 credit short of a math minor). I have been out of college for about six years now and working as a software developer during that time. Off and on since leaving college I have been self-teaching myself physics. Sometimes I daydream of going back for graduate school and getting a masters (or more) in physics. I am particularly fascinated by quantum computers, and my best case scenario is if I could find a graduate program where I could somehow be involved in quantum computer research-- in fact, I'm mostly interested in the idea of grad school because this is how I imagine one would get involved with quantum computing research right now. Some questions-- 1. Is this idea-- going for physics graduate school, after a non-physics undergrad degree-- even possible? 2. If I were to attempt to apply for physics graduate school, what would I need to do or how would I need to prepare for it? (Assume I'm okay with the idea of an answer to this question being something that takes years to implement…) 3. I have this idea in my head that if I specifically try to focus on quantum computers or the theory of quantum information, that it might make it easier to get into a program without having physics credentials ahead of time because quantum computing exists to an extent at an intersection of fields-- you need to be able to understand not just ideas from physics but also from computational complexity theory or information theory, so I imagine some programs might be amenable to letting in a CS person who can come in saying "I understand complexity theory very well but I need more education on physics". Is this line of thought realistic at all? Thanks.
