Invariances for states of light and their quasi-distributions Academic Article

abstract

• We consider the states of a two-mode light field which are invariant under rotation of the coordinate axis. We derive the general form of Wigner, Q and P functions as well as the density matrix. On imposing further invariances we recover the results for the unpolarized radiation of different kinds.
