Abstract :
We have measured the Wigner function of the vacuum and of a one photon field state prepared in a high Q cavity. We implement a method proposed by Lutterbach and Davidovich. The field state is prepared in a high Q superconducting microwave cavity and measured by a single circular Rydberg atom which is strongly coupled to the cavity mode. An analysis of the measured Wigner function allows to reconstruct efficiently the actual photon number distribution of the prepared field.
