The equation of motion of the quantum characteristic function for the linear-algebraic dynamical system is derived from the von Neumann equation and reduced to a Schr\"odinger-like equation in a differential adjoint representation. The exact analytical solution to the von Neumann equation of the quantum characteristic function of the two-level Jaynes-Cummings model is obtained.
