One-probe reconstruction of a quantum state
Dmitri S. Mogilevtsev · Physical Review A · 1998
In this work we demonstrate a possibility to reconstruct a density matrix of a single-mode signal state of radiation field using a two-detector measurement scheme with fixed position of beam splitter and identical probe states for both ideal and nonideal detectors. It is also shown that by using different probe states in this measurement scheme it is possible to make the reconstruction measuring only the probability of no photon registration on both nonideal detectors.
