a,b, Single-mode Wigner functions measured at frequencies \({f}_{1}\) and \({f}_{2}\) at a pump power P = 28.6 mW below the parametric pumping threshold at 220 K under B = 30.14 mT. c,d, Two-mode Wigner functions of the I and Q quadratures measured at the same power as in a,b. e,f, Single-mode Wigner functions measured at \({f}_{1}\) and \({f}_{2}\) for P = 29.1 mW above the threshold. g,h, Two-mode Wigner functions of the I and Q quadratures measured at P = 29.1 mW.
