Abstract Polarization multi-photon quantum state tomography with non-unit quantum efficiency of detectors is considered. A new quantum tomography protocol is proposed. This protocol considers the event of losing photons of a multi-photon quantum state in one or more channels among with n -fold coincidence events. The advantage of the proposed protocol compared with the standard n -fold coincidence protocol is demonstrated using methods of statistical analysis.
