The generation of high Fock states of light with provable quantum non-Gaussian features is still very challenging, although the power of conditional methods to herald the approximate state from the available Gaussian states is growing. The atom-light interaction in the high-Q cavity has been considered a viable alternative to the heralded Fock states from nonlinear optics limited to three-photon Fock states for the last decade. In the presentation, combining atom-light interaction with available optical delay elements, we conclusively predict filtering of the Fock states of up to ten photons with a high success rate of 20% using a hierarchy of quantum non-Gaussian criteria. To demonstrate their quality for applications, we evaluate the robustness of such features, the bunching capability in a linear network, and the sensing capability to estimate the magnitude of unknown force and noise.
