Based on the path integral approach,we derive a new realization of the exact non-Markovian stochastic Schr(o)dinger equation(SSE).The main difference from the previous non-Markovian quantum state diffusion(NMQSD)method is that,the complex Gaussian stochastic process used for the forward propagation of the wave function is correlated,which may be used to reduce the amplitude of the non-Markovian memory term at high temperature.
