    "abstract": "We study quantum correlations and quantum noise in the soliton collision\ndescribed by a general two-soliton solution of the nonlinear Schr\\\"odinger\nequation, by using the back-propagation method. Our results include the\nstandard case of a $sech$-shaped initial pulse analyzed earlier. We reveal that\ndouble-hump initial pulses can get more squeezed, and the squeezing ratio\nenhancement is due to the long collision period in which the pulses are more\nstationary. These results offer promising possibilities of using higher-order\nsolitons to generate strongly squeezed states for the quantum information\nprocess and quantum computation.",
