Figure 7

A parametric plot of the normalized measure of \(\pmb{\nu(\psi_{0})}\) nonclassicality based on the negative parts of the Wigner-function for the GS of the driven Duffing resonator as a function of the nonlinearity measure \(\pmb{\eta_{ { \mathrm{N G}} } [{V} ]}\) (parameters \(\pmb{\varepsilon=0.01}\) , \(\pmb{t=1}\) , \(\pmb{\omega=1.018}\) , and \(\pmb{\mathcal{F}=0.015}\) ) appears to be roughly linear and monotonically increasing.
