Hybrid quantum communication and computation — •Peter van Loock — Institute of Theoretical Physics I, Univ. Erlangen-Nuremberg, Erlangen, Germany — OQI Group, MPL, Erlangen, Germany

We give an overview of our group’s investigations into optical hybrid approaches to quantum communication and information processing, in which discrete and continuous degrees of freedom are exploited at the same time. These include various notions and applications such as hybrid entanglement, hybrid quantum repeaters for long-distance quantum communication, and small-scale quantum logic using hybrid resources. Our most recent emphasis is on the issue of imperfect memories in a quantum repeater and the choice between entanglement distillation and quantum error correction, as well as on the possibility of implementing nonlinear gates using both Gaussian and non-Gaussian resource states.
