Abstract  By starting from the stochastic Schr odinger equation and quantum trajectory theory, we introduce memory effects by considering stochastic adapted coefficients. As an example of a natural nonMarkovian extension of the theory of white noise quantum trajectories we use an OrnsteinUhlenbeck coloured noise as the output
driving process. Under certain conditions a random Hamiltonian evolution is recovered. Moreover, we show that our nonMarkovian stochastic Schr odinger equations unravel some master equations with memory kernels.
