Query: Absolute self-calibration of single-photon and multiplexed
  photon-number-resolving detectors   Single-photon detectors are widely used in modern quantum optics experiments
and applications. Like all detectors, it is important for these devices to be
accurately calibrated. A single-photon detector is calibrated by determining
its detection efficiency; the standard method to measure this quantity requires
comparison to another detector. Here, we suggest a method to measure the
detection efficiency of a single photon detector without requiring an external
reference detector. Our method is valid for individual single-photon detectors
as well as multiplexed detectors, which are known to be photon number
resolving. The method exploits the photon-number correlations of a nonlinear
source, as well as the nonlinear loss of a single photon detector that occurs
when multiple photons are detected simultaneously. We have analytically modeled
multiplexed detectors and used the results to experimentally demonstrate
calibration of a single photon detector without the need for an external
reference detector.
