Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) I show that calibration of the single-photon detector can be performed without knowledge of the signal parameters. Only partial information about the state statistics is sufficient for that. If one knows that the state is the squeezed one or the squeezed one mixed with the incoherent radiation, one can infer both the parameters of the state and the efficiency of the detector. For that one needs only to measure on/off statistics of detector clicks for the number of known absorbers placed before the detector. Thus, I suggest a scheme that performs a tomography of the signal and the measuring apparatus simultaneously. 82 2 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) BRFFI of Belarus Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)
