We derive a closed photo-counting formula, including noise counts and a finite quantum efficiency, for photon number resolving detectors based on on/off detectors. It applies to detection schemes such as array detectors and multiplexing setups. The result renders it possible to compare the corresponding measured counting statistics with the true photon number statistics of arbitrary quantum states. The photo-counting formula is applied to the discrimination of photon numbers of Fock states, squeezed states, and odd coherent states. It is illustrated for coherent states that our formula is indispensable for the correct interpretation of quantum effects observed with such devices.

We present a general method to detect nonclassical radiation fields with systems of on-off detectors. We especially study higher order correlations for the identification of nonclassical radiation. This allows us to directly characterize quantum correlations by the statistics measured with systems of on-off detectors. Additionally, we generalize our method to multiple detector systems for measurements of correlations between light fields. We also consider multi-mode radiation fields and isolate nonclassicality in terms of the space time correlations. Finally, we present results for the quantum statistics using on-off detectors operating in nonlinear detection modes.

“…Ideally, the detector elements would be connected to an integrated circuit capable of providing readout for a large number of elements, as has been demonstrated for Geiger-mode avalanche photodiodes [12]. While work on such a readout-integrated circuit progresses, reading out a small number of elements using discrete electronics is feasible.…”

“…One often cited advantage of the multiplexing approach in general is that it can be used to transform any single-photon-sensitive detector technology into a photon-number-resolving detector, including technologies that operate near room temperature. Applications requiring compact photonnumber-resolving detectors may benefit from this approach, which has been demonstrated for both spatial [12] and temporal [13][14] multiplexing. However, one advantage unique to spatial multiplexing is the ability to create a photon-number-resolving detector with higher performance, particularly in terms of the maximum counting rate and timing resolution.…”

A photon-number-resolving detector based on a four-element superconducting nanowire single photon detector is demonstrated to have sub-30-ps resolution in measuring the arrival time of individual photons. This detector can be used to characterize the photon statistics of non-pulsed light sources and to mitigate dead-time effects in high-speed photon counting applications. Furthermore, a 25% system detection efficiency at 1550 nm was demonstrated, making the detector useful for both low-flux source characterization and high-speed photon-counting and quantum communication applications. The design, fabrication and testing of this detector are described, and a comparison between the measured and theoretical performance is presented.Keywords: photon-number-resolution; superconducting nanowire single photon detector; timing jitter; system detection efficiency _____________________ *Corresponding author.
