摘要

We introduce the intermediate entangled state |α> and discuss its properties of|α>λ,ν. We obtain the expression of the two-mode Wigner operator in the |α>λ,ν representation. We find that the projection operator |α>λ,νλ,ν <α| is just the Radon transformation of the two-mode Wigner operator. Using the |α> λ,ν representation, we successfully obtain the eigenvalues and eigenvectors of a bipartite system coupled in a quite complicated way.
