    "abstract": "We have developed a method for calculation of quantum fluctuation effects, in\nparticular of the uncertainty zone developing at the potential curvature sign\ninversion, for a damped harmonic oscillator with arbitrary time dependence of\nfrequency and for arbitrary temperature, within the Caldeira-Leggett model. The\nmethod has been applied to the calculation of the gray zone width Delta Ix of\nJosephson-junction balanced comparators driven by a specially designed\nlow-impedance RSFQ circuit. The calculated temperature dependence of Delta Ix\nin the range 1.5 to 4.2K is in a virtually perfect agreement with experimental\ndata for Nb-trilayer comparators with critical current densities of 1.0 and 5.5\nkA/cm^2, without any fitting parameters.",
