Photon-number discrimination without a photon counter and its application to reconstructing non-Gaussian states
The nonlinearity of a conditional photon-counting measurement can be used to "de-Gaussify" a Gaussian state of light. Here we present and experimentally demonstrate a technique for photon-number resolution using only homodyne detection. We then apply this technique to inform a conditional measurement, unambiguously reconstructing the statistics of the non-Gaussian one- and two-photon-subtracted squeezed vacuum states. Although our photon-number measurement relies on ensemble averages and cannot...[Show more]
