New Approach for Calculating Wigner Functions of Generalized Two-Mode Squeezed State and Squeezed Number State via Entangled State Representation
摘要
We construct the generalized squeezed vacuum state by virtue of the entangled state 〈η| [Fan Hongyi and J.R. Klauder, Phys. Rev. A47 (1994) 777] and derive the quantum fluctuation of the two-mode quadrature operators.We then calculate Wigner functions of the two-mode squeezed number states and generalized squeezing vacuum state in literature before.
