摘要

By virtue of the Weyl-Wigner quantization scheme, we derive the explicit form of the squeezing-enhanced state without disentangling the generalized squeezing operator exp[-iλ/2(Q~2e~r - e~(-r) P~2)], where Q and P are two quadratures of the light field; this approach is convenient and concise. By virtue of the Weyl-ordering invariance under similar transformations, the Wigner function of the squeezing-enhanced state is derived and its figure is depicted, which clearly exhibits the squeezing enhancement.
