Abstract: | The concept of P-quasispin is used as a framework for developing a formalism for polarization transformation by means of lossless polarization-changing
optical elements for both classical and quantum multimode light fields. As an example, a classification of transformations
of this kind is presented for two-mode biphoton fields that implement the information-theoretic concepts of qutrit and ququart
(quantum systems in three-and four-dimensional Hilbert states, respectively).
