Detection-device-independent verification of nonclassical light
Martin Bohmann, Luo Qi, Werner Vogel, Maria Chekhova · Physical Review Research · 2019
The authors present an approach for the detection-device independent verification of nonclassical light. This method applies to any multiplexing system with on-off detectors, and works for both unequal splitting ratios and uncharacterized detectors. The derived nonclassicality conditions yield highly significant verifications of the quantum nature of light from clusters of single-photon emitters, which is detected through time-bin multiplexing.
