The Technical University of Dortmund has an opening for a PostDoc working on the implementation of photonic quantum memories on the basis of rare-earth ion crystals. The successful candidate should design an implement experiments that store photons in the crystals, convert them to nuclear spin degrees of freedom and protect them against environmental perturbations. The project is integrated in the EU-ITN CIPRIS (http://www.cipris.eu/). Additional information is available at http://e3.physik.tu-dortmund.de/~suter/research/REI_QIP.pdf. Candidates should have a strong background in laser spectroscopy, magnetic resonance and / or quantum information processing.
