New representation for squeezing-rotating entangled unitary transformation

We introduce a new unitary operator U which can engender a squeezing and ro tating entangled transformation. The U operator has a concise expression in a new representation in two-mode Fock space. The normally ordered form of U can be derived by using the technique of integration within an ordered pr oduct of operators. The fluctuation in quadrature phases for these squeezin g-rotating entangled states are analyzed.
