I am an undergraduate student and I would like to approach the subject of topological order with focus on topological quantum computation, I know (very) little QFT and basic algebraic topology (if that matters...).
To give a reference frame, I'd like to understand papers like http://arxiv.org/abs/quant-ph/9707021 or Preskill's great presentations: http://online.kitp.ucsb.edu/online/exotic_c04/preskill/, and later to take it as my field of research for a PhD.
So my questions are:
What kind of studies are useful/needed for this field? I assume Quantum Computation/Information are, but what else? Quantum Field Theories, Topology, Quantum Optics?
Which are universities or research centers active in the field (preferably in Europe)?
Any reference suggested? (Better if beginner-focused)
