A non-Gaussian system is one for which the outputs do not obey Gaussian statistics. In the continuous-variable regime, this normally means a nonlinearity of higher than second order in the interaction Hamiltonian. Well known systems meeting this criterion are trapped Bose-Einstein condensates and optical fibres. This project will first look at ways to produce single-mode non-Gaussian outputs of the electromagnetic field, either by interaction within a fibre or by "statistics swapping"from trapped condensates. It will then investigate ways in which these outputs may be manipulated to produce non-Gaussian entangled states for potential use in quantum information technologies.
