This chapter is devoted to applications of the coherent emission of two subgroups of photons, the sum (or difference) energies of which can be regarded as a constant, so that coherence appear between the blocks of photons, belonging to different modes of the electromagnetic field. As it was shown, themulti-mode broadband squeezed light can be described by the coherent states of the bimodal electromagnetic field. The application of coherent effect of bimodal field in holography opens the new perspectives in the transmission of information not only through entangled state of photons but also through the second order coherence. This method of recording of information opens the new perspectives in quantum cryptography and quantum information. At the first glance one observes that such hologram registration of information may have nothing to do with the traditionalmethod. If the photon-pair pulses pass through a dispersive medium, the "idler" photons from the each pair change their directions relative to "signal" photons. Focusing the "signal" and "idler" photons into different optical fibers, we can observe the total destroyed of coherence among the photons. However, after a certain propagation distance, the "idler" and "signal" photons from the pairs may be mixed again, and we may observe, that the coherence is restored. The image, obtained in two-photon holograms takes into account not only entanglement between the pair photons, but the coherence between photon pairs, and can be used in mixed processing problems in which the quantum entanglement between the pair photons is used together with classical coherence between the photon pairs. Of course the probability of experimental realization of logic gates for quantum circuits in this case increases. More than this similar coherent description may be exported to bimodal electromagnetic field, formed from the Stokes and anti-Stokes modes in the cooperative Raman emission.
