Experimentally verifiable criteria of non-Gaussian coherences
We introduce a hierarchical framework using absolute, relative, and qubit-specific thresholds assessing non-Gaussianity and non-classicality in local coherences. We generate high purity superpositions of 1- and 2-photons with vacuum that surpass the specified criteria.
