Non-Gaussian states and entanglement distillation for Continuous Variable quantum information protocols

If most basic quantum communication protocols have already been demonstrated, they still require improvements in current quantum technologies to revolutionize everyday communications. This proposal aims to develop such new technologies. Using Continuous-Discrete hybrid systems we will investigate the production of highly non-Gaussian states that would gather advantages of both (previously separated) CV and DV domains. We will also build a (non-deterministic) linear noiseless amplifier, which will be used (among many other potential applications) to distillate entanglement. This is a key step toward achievement of quantum repeaters, a technology in high demand that would enable quantum communications over large distances.
