我们发展了色散非线性介质中传播的量子理论。量子涨落是通过相干态正p表示来处理的。得到了场变量中的随机非线性Schrödinger方程，该方程预测了异常色散区域的宽带压缩。对于孤子输入，波动在孤子带宽上被减小。这导致量子孤子的正交涨落小于真空涨落的水平。
We develop a quantum theory of propagation in dispersive nonlinear media. Quantum fluctuations are handled via the coherent-state positive-P representation. A stochastic nonlinear Schrödinger equation in the field variables is obtained which predicts wide band squeezing in the region of anomalous dispersion. For soliton inputs, fluctuations are reduced over the soliton bandwidth. This leads to quantum solitons which have quadrature fluctuations less than the level of vacuum fluctuations.
