"Gaussian states and Gaussian operations hold a prominent place within continuous variables(CV) quantum information theory. However, the ease of both experimental and theoreticaltreatment does not come without a cost - there are limits in what Gaussian states andoperations can do. For example, although they can be employed by CV quantum cryptography,protocols such as entanglement distillation and quantum computation are out of theirreach. These are the tasks that require non-Gaussian resources, obtainable by nonlinearprocesses of order higher than two. However these processes, represented for example bythe Kerr nonlinearity, are difficult to implement with required quality. Our goal is to takeadvantage of the measurement induced paradigm and find ways of obtaining and manipulatinghigh-order nonlinearities not directly, but with help of off-line non-Gaussian statesand non-Gaussian measurements."@en . .
