Quantum Non-Gaussian and Highly Nonlinear Physics

Quantum physics with light and mechanical oscillators already broke in various platforms the long-standing limitations of Gaussian states and linear interactions. Quantum non-Gaussian states of light and mechanical oscillators are generated with increasing quality and considered for applications. However, it is only the beginning of many possible journeys in this unknown and uncovered territory of physics where quantum noise combines with strong and exotic nonlinear effects. It is both challenging and stimulating investigation in tightly-connected theory and experiments. It is highly expected that these discoveries will bring unexpected quantum phenomena and applications of continuous-variable systems. The talk will present recent theoretical and experimental achievements in quantum non-Gaussian state preparation of photons and phonons and their diagnostics by new theoretical tools.

We will continue with the results in highly nonlinear physics with cubic nonlinearity for light and mechanical motion. The conclusion will address the next challenges of this exciting field.
