# Efficiencies of quantum optical detectors

@article{Hogg2014EfficienciesOQ, title={Efficiencies of quantum optical detectors}, author={D. Hogg and Dominic W. Berry and A. I. Lvovsky}, journal={Physical Review A}, year={2014}, volume={90}, pages={053846} }

We propose a definition for the efficiency that can be universally applied to all classes of quantum optical detectors. This definition is based on the maximum amount of optical loss that a physically plausible device can experience while still replicating the properties of a given detector. We prove that detector efficiency cannot be increased using linear optical processing. That is, given a set of detectors, as well as arbitrary linear optical elements and ancillary light sources, it is…
