A novel quantum mechanical formulation of time correlation functions is derived, based on Bohmian trajectories integrated along a forward-backward time contour. The derived expression involves a smooth integrand amenable to Monte Carlo integration with a readily available position space density. The Bohmian potential governing the motion of the quantum trajectories is weak and well-behaved, facilitating the computation of Bohmian trajectories.
