    "abstract": "Although the National Institute of Standards and Technology has measured the\nintrinsic quantum efficiency of Si and InGaAs APD materials to be above 98 % by\nbuilding an efficient compound detector, commercially available devices have\nefficiencies ranging between 15 % and 75 %. This means bandwidth, dark current,\ncost, and other factors are more important than quantum efficiency for existing\napplications. This paper systematically examines the generic detection process,\nlays out the considerations needed for designing detectors for non-classical\napplications, and identifies the ultimate physical limits on quantum\nefficiency.",
