An approach to study the noise characteristics in mesoscopic devices is presented. It extends, via quantum trajectories, the classical particle Monte Carlo techniques to devices where quantum nonlocal effects are important. As a numerical example, the fluctuations of the electron current through single-tunnel barriers are compared with the standard Landauer - Buttiker results, showing an excellent agreement. © 2001 American Institute of Physics.
