摘要：

Two algorithms for measuring the polarization state of the biphoton field prepared in the form of a three-level system (qutrit) are considered. On the basis of the general approach developed by Klyshko [21] for describing the polarization properties of single-mode electromagnetic fields in the fourth order in the field, a procedure for measuring the polarization density matrix of qutrits is proposed and implemented.
