Query: Simultaneous, full characterization of a single-photon state using
  semiconductor quantum-dot light   As single-photon sources become more mature and are used more often in
quantum information, communications and measurement applications, their
characterization becomes more important. Single-photon-like light is often
characterized by its brightness, and two quantum properties: the single-photon
composition and the photon indistinguishability. While it is desirable to
obtain these quantities from a single measurement, currently two or more
measurements are required. Here, we simultaneously determine the brightness,
the single photon purity, the indistinguishability, and the statistical
distribution of Fock states to third order for a quantum light source. The
measurement uses a pair of two-photon (n = 2) number-resolving detectors. n > 2
number-resolving detectors provide no additional advantage in the single-photon
characterization. The new method extracts more information per experimental
trial than a conventional measurement for all input states, and is particularly
more e cient for statistical mixtures of photon states. Thus, using this n=2,
number- resolving detector scheme will provide advantages in a variety of
quantum optics measurements and systems.
