The Q-function is obtained by solving the Fokker-Planck equation applying the propagator method developed by Fesseha [lJ. We also calculate the squeezing spectra of the output quadrature operators using the quantum Langevin equationsenA Degenerate ParametricA Degenerate Parametric Oscillator Coupled to a Squeezed VacuumThesis
