    "abstract": "We predict phase-transitions in the quantum noise characteristics of systems\ndescribed by the quantum nonlinear Schr\\\"odinger equation, showing them to be\nrelated to the solitonic field transition at half the fundamental soliton\namplitude. These phase-transitions are robust with respect to Raman noise and\nscattering losses. We also describe the rich internal quantum noise structure\nof the solitonic fields in the vicinity of the phase-transition. For optical\ncoherent quantum solitons, this leads to the prediction that eliminating the\npeak side-band noise due to the electronic nonlinearity of silica fiber by\nspectral filtering leads to the optimal photon-number noise reduction of a\nfundamental soliton.",
