本文在量子光学的背景下,将普通的二项式定理推广到二元Hermite多项式的情形,并解析地得到了几个新的广义二项式定理,其结果与单模或双模Hermite多项式的结果完全相同。作为它们在量子光学中的应用,我们解析地证明了多光子压缩态bnesa B +ra| 00 μ π ι等价于厄米多项式加权量子态作为一种容易产生的非高斯纠缠信息源,自旋相干态的Wigner函数及其边缘分布分别为Laguerre多项式和Hermite多项式.
AbstractWe extend the ordinary binomial theorem to the case which involves two-variable Hermite polynomials in the context of quantum optics, and analytically obtain several new generalized binomial theorems whose results exactly equal the single- or two-mode Hermite polynomials. As their applications in the field of quantum optics, we analytically prove that the multiple-photon-subtracted squeezed stateambnesa†b†+ra†+tb†|00⟩ is equivalent to the Hermite-polynomial-weighted quantum state serving as an easily produced non-Gaussian entangled information resource, and the Wigner functions of spin coherent states and their marginal distributions are respectively the Laguerre polynomials and the Hermite polynomials.Graphical abstract
