19. A delicate point in homodyne tomography is the choice of phases (Formula presented) for quadrature measurements. The safest sampling method that avoids systematic errors consists in making the phase a uniformly distributed random parameter 7. The estimation procedure developed in the remaining part of the paper is based on this assumption. In a typical experiment; however, homodyne statistics are collected for a finite set of equidistant phases. If the phase sampling is sufficiently dense, such data can be processed using the algorithm presented, as illustrated further by the numerical example. For a discussion of the number of phases, see U. Leonhardt and M. Munroe, Phys. Rev. A 54, 3682 (1996).
