负二项式态量子叠加的统计性质和代数特征

Statistical Properties and Algebraic Characteristics of Quantum Superpositions of Negative Binomial States

Xiao-Guang Wang, Hong-Chen Fu

摘要:

我们引入了量子化辐射场的新态,它们是负二项式态的叠加。它们表现出显著的非经典性质,并在一定的极限下还原为薛定谔猫态。在偶数和奇数负二项态所涉及的代数原来是一般变形振子代数。研究发现,偶、奇负二项式态满足相同的本征方程,具有相同的本征值,可以看作是双光子非线性相干态。提出了两种产生这种状态的方法。

英文摘要:

We introduce new kinds of states of quantized radiation fields, which are the superpositions of negative binomial states. They exhibit remarkable non-classical properties and reduce to Schrödinger cat states in a certain limit. The algebras involved in the even and odd negative binomial states turn out to be generally deformed oscillator algebras. It is found that the even and odd negative binomial states satisfy a same eigenvalue equation with a same eigenvalue and they can be viewed as two-photon nonlinear coherent states. Two methods of generating such states are proposed.
