Paper Abstract

The shot noise limit is a fundamental lower limit on the sensitivity of any measurement and is de ned by nature. We propose an experiment in which we measure the di erence current from each heterodyne detector and nd that the result is a sinusoidal function of the path length di erence between the the two heterodyne systems. For certain values of the path length, we expect to overcome the shot noise limit set by the local oscillator. Here we review our experiment and report on the current experimental progress.
