Sufficient condition for a quantum state to be genuinely quantum non-Gaussian
We show that the expectation value of the operator $\hat{{ \mathcal O }}\equiv \exp (-c{\hat{x}}^{2})+\exp (-c{\hat{p}}^{2})$ defined by the position and momentum operators $\hat{x}$ and $\hat{p}$ with a positive parameter c can serve as a tool to identify quantum non-Gaussian states, that is states...
