| The coupled mesoscopic systems offer an ideal stage to investigate the electron interaction through pure long-range Coulomb forces and/or the photon emission from the non-equilibrium systems. We report an experiment of the non-local detection of the shot noise in the double quantum point contact (QPC) system. We use one QPC as a noise source and the other QPC as a detector, and successfully detect the non-equilibrium noise from the source by means of the noise measurement. |
