  "abstract": "A new theorem on the non-classicality depth of states has been proved. We show that if $W_{\\hat \\rho} (\\alpha_m,s_m)=0$ exist for some value of the ordering parameter $s$ at some phase-space point $\\alpha_m$, and if $W_{\\hat \\rho} (\\alpha,s_m)$ is an acceptable quasi-classical distribution, the non-classicality of $\\hat \\rho$ in parallel with Lee's non-classicality depth is then given by $\\tau_m=(1 - s_m)/2$. In this way, a general examination of the effects of the single-photon-addition and -subtraction operations has been studied. The theorem, indeed, provides a theoretical background for generating quantum states of arbitrary non-classicality depth.",
