Do any of you know of the reputation of the Max Planck institute in Erlangen? I'm going into quantum optics, so the work they do there is relevant to my studies, but their reputation in comparison to, say, CalTech or MIT is completely unknown to me. And yes, I realize that the Institute is not a university, I would be doing my pHd out of University Complutense de Madrid, but all my research would be done at the institute. Any thoughts? Has anyone here actually done or is doing research at the Institute?
