Two senior postdoc positions are available within experimental quantum optics at the Niels Bohr Institute, University of Copenhagen. The position(s) will be part of the experimental quantum photonics group and the Center for Hybrid Quantum Networks (Hy-Q) headed by Profs. Peter Lodahl and Anders. S. Sørensen. The successful candidates will be responsible for leading and developing the existing activities within coupled quantum emitters and spin-photon interfaces and will be the daily supervisor of the Ph.D. students working on the projects. For experienced applicants the position can potentially be upgraded to a (non-tenure track) assistant professor position after a short time.
