    "abstract": "A fast simulation algorithm for the calculation of multitime correlation\nfunctions of open quantum systems is presented. It is demonstrated that any\nstochastic process which ``unravels\u0027\u0027 the quantum Master equation can be used\nfor the calculation of matrix elements of reduced Heisenberg picture operators,\nand thus for the calculation of multitime correlation functions, by extending\nthe stochastic process to a doubled Hilbert space. The numerical performance of\nthe stochastic simulation algorithm is investigated by means of a standard\nexample.",
