In this paper, the solution of the time-dependent Fokker–Planck equation of non-degenerate optical parametric amplification is used to deduce the condition demonstrating the Einstein–Podolsky–Rosen (EPR) paradox. The analytics and numerical calculation show the influence of pump depletion on the error in the measurement of continuous variables. The optimum realization of EPR paradox can be achieved by adjusting the parameter of squeezing. This result is of practical importance when the realistic experimental conditions are taken into consideration.

In this paper, we use the solution of the Fokker-Planck equation for non-degenerate parametric amplification to deduce the condition of demonstration of the EPR paradox. The numerical simulation shows that the optimum realization of EPR paradox can be achieved by adjusting the degree of squeezing, and this is the best condition for demonstrating the EPR paradox for a given finite loss k.
