After 3 years of udergraduate study I need to decide on my Master Degree program (which is very specialized here in EU). I really hate programming and experimental stuff while I am very interested in mathematical approach so I want to do theoretical physics (with no computional aspects). However I am not sure which subject should I choose since courses or REUs are not enough for me to know certain subject very well. I am interested in some ("fundamental") aspects of quantum gravity, quantum computing and superconductivity. Could you tell me sth more about this subjects in terms of job prospects (in my country job in academia isn't as hard to get as in US but it's good if your field has some real-life applications especially in bio and nano (some mathematical methods used in HEP are useful in bio so you can get money and still do astrophysics), breakthroughs, results confirmed by experiments, chances for not doing numerical modelling and much more. I would like to hear more about those subjects from people who are (or used to be) in those fields.
