Abstract.

For an asymmetric beam-splitter a new kind of entangled state \(\left| \eta ,\theta \right\rangle \) is introduced, we then derive the integration measure with which such states can make up a complete and orthonormal representation in two-mode Fock space. We then show how to use \(\left| \eta ,\theta \right\rangle \) in finding new squeezing operator and new squeezed state, whose generation can relies on the asymmetric beamsplitter.
