Query: Characteristics of displaced single photons attained via higher order
  factorial moments   We investigate up to the fourth order normalized factorial moments of
free-propagating and pulsed single photons displaced in phase space in a
phase-averaged manner. Due to their loss independence, these moments offer
expedient methods for quantum optical state characterization. We examine
quantum features of the prepared displaced states, retrieve information on
their photon-number content and study the reliability of the state
reconstruction method used.
