QUROPE Quantum Information Processing and Communication in Europe

Location

 Applications are invited for two postdoctoral positions in experimental quantum optics and quantum information at Laboratoire Kastler Brossel (LKB), in Paris (France). LKB is jointly run by Université P. et M. Curie, Ecole Normale Supérieure and CNRS. The quantum optics group has a worldwide-recognized position on the study and manipulation of quantum fluctuations of light and atoms, aiming at demonstrating new tools for information processing.

The proposed research is included in the starting European project “QSCALE: Extending the range of quantum communications”. It aims at experimentally demonstrating photonic and atomic components enabling the development of quantum repeaters and their integration into quantum communication and processing networks. QSCALE includes 6 European partners coordinated by the LKB team. The successful applicants will play a key role in this cutting-edge and stimulating consortium.

Two positions are opened:
- The first position will focus on the experimental development of photonic components for quantum architectures, state engineering, and quantum computing. Specifically, the project will be concerned with the development of a hybrid approach for quantum information processing, where continuous-variables of light and photon counting are mixed. The general aim is to develop the toolbox for this approach, including high-purity Schrödinger cat generation, which can be used for information encoding, and to demonstrate its use for applications in the distribution and processing of quantum information (e.g. entanglement distillation, hybrid quantum repeaters, gates for quantum computing with superposed coherent states).
- The second position will focus on the development of efficient optical quantum memories with large ensemble of cold atoms. The candidate will be responsible of an experiment aiming at demonstrating long-lived storage of quantum states and controlling interaction between remote memories, an important requisite for scalable quantum networks. He will also actively participate to the study of novel architectures for quantum repeaters based on hybrid schemes involving continuous variables and single-photon counting. 
Application procedure: Inquiries and applications should be sent by email to Julien Laurat (julien [dot] laurat [at] upmc [dot] fr). Applications should include a detailed CV, a brief statement of research interests and two names of potential referees. The call will remain open until the two suitable candidates are identified.
