We consider a new approach of the SU(3)-symmetry polarization in Hubert space for a quantum Bose-system with internal Gell-Mann symmetry in quantum and atomic optics. The operational determination of the SU(3) phase problem for a three mode optical field is discussed for the first time. The original twelve-port interferometer for simultaneous measurements of both the Gell-Mann parameters and the phase characteristics is proposed. The signal-to-noise ratio coefficients for coherent end entangled states of light are examined. In the paper we also discuss application ofour theory for the problems of quantum information as well.
