Tomography of multi-photon polarization states in conditions of non-unit quantum efficiency of detectors
arXiv:1711.02964 · doi:10.1088/1555-6611/aa9a9f
Abstract
The polarizing multi-photon quantum states tomography with non-unit quantum efficiency of detectors is considered. A new quantum tomography protocol is proposed. This protocol considers events of losing photons of 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 the methods of statistical analysis.
