New Representation for Squeezing-Rotating Entangled Unitary Transformation
Fan Hong-Yi, Fan Yue · Communications in Theoretical Physics · 2000
We introduce a new unitary operator which can engender a squeezing and rotating entangled transformation. The operator has a concise expression in a new representation in two-mode Fock space. The normally ordered form of can be derived by using the technique of integration within an ordered product of operators. The fluctuation in quadrature phases for these squeezing-rotating entangled states are analyzed.
