Time-dependent POVM reconstruction for single-photon avalanche photo diodes using adaptive regularization

We report on the first realization of time-dependent quantum detector tomography for commercially available InGaAs avalanche photo detectors. For the construction of appropriate time-dependent POVMs from experimentally measured data, we introduce a novel scheme to calculate the weight of the regular...
