“…calibration and traceability (instead of using standard sources and detectors), with higher photon flux and counts, a method was developed based on the twin photon current technique. [ 95 ] Here, the absolute quantum efficiency was calculated using the photon counts obtained by converting each PMT current output. The relative standard uncertainty achieved using this method was 2.1%.…”

The evolution of quantum standards for SI units and funding support from national governments has led to rapid technological developments in the quantum sciences. With this, new and more powerful quantum optical devices that find applications in several fields are obtained. Single‐photon detectors (SPDs) are considered as a critical element in these emerging technologies. A traceability chain for SPD calibration is required to ensure their performance reliability and quality. Different methods and techniques are being developed worldwide for the calibration of SPDs. In this paper, the developments that have occurred globally in SPD calibration and the uncertainty value achieved until now are summarized along with the scope of possible improvement areas.

A photodetector signal-to-noise ratio (SNR) over 1000 is one of the prerequisites to realizing the correlated photon radiometric benchmark with a relative standard uncertainty of 0.3% (k=1). To improve the SNR for low-photon flux detection, a switched integration amplifier (SIA) is designed to achieve a noise equivalent current of a fA level. A wide spectrum and low-photon flux measurement facility are built to evaluate the SNR at a photon rate of 108s−1 within the spectral range of 350–1000 nm. SNRs of the SIA-based Si photodetector are shown to be greater than 1000 at representative wavelengths.
