Randomized trial demonstrates high-quantum-efficiency in photon detection, indicating significant advancements in optical technology.

The aim is to develop a single-photon counting system with high quantum efficiency.
Developed a visible light photon counter operated at 6.9 K.
Implemented threefold tight shielding and infrared blocking filters to minimize dark counts.
Measured dark counts and quantum efficiencies at varying temperatures and bias voltages.
Achieved corrected quantum efficiencies as high as 88.2%±5% at 694 nm, the highest reported for single-photon detectors.
Observed a dark count of 2.0×10^4 cps at maximum quantum efficiency, with its increase related to temperature and bias voltage changes.

Takeuchi et al. (1999) studied this question.
