Abstract
By using a quantum point contact as a charge detector, we show the measurement of current fluctuations in a semiconductor quantum dot by counting electrons tunneling through the system one by one. This method gives direct access to the full counting statistics of current fluctuations. In the sequential tunneling regime, we show the suppression of the noise compared to its classical Poissonian value, which is expected due to Coulomb blockade.
