Query: Photon-number parity of heralded single photons from a Bragg-reflection
  waveguide reconstructed loss-tolerantly via moment generating function   Due to their strict photon-number correlation, the twin beams produced in
parametric down-conversion (PDC) work well for heralded state generation.
Often, however, this state manipulation is distorted by the optical losses in
the herald and by the higher photon-number contributions inevitable in the PDC
process. In order to find feasible figures of merit for characterizing the
heralded states, we investigate their normalized factorial moments of the
photon number that can be accessed regardless of the optical losses in the
detection. We then perform a measurement of the joint photon statistics of twin
beams from a semiconductor Bragg-reflection waveguide with transition-edge
sensors acting as photon-number-resolving detectors. We extract the
photon-number parity of heralded single photons in a loss-tolerant fashion by
utilizing the moment generating function. The photon-number parity is highly
practicable in quantum state characterization, since it takes into account the
complete photon-number content of the target state.
