论文摘要

在量子光学元件中,经常研究各种辐射场的非经典特性。其中一些状态是有限的维度,称为Qudits。这些状态很重要,因为它们在量子信息处理中的潜在应用。此外,非经典状态是没有任何经典的国家。因此,要建立量子至上,我们始终需要非规范状态。最近,Sivakumar和Meher研究了数字状态过滤相干状态的非经典属性,并表明数字状态过滤将非经典特征引入了相干状态,这是经典的。这一观察结果促使我们研究孔燃烧(状态过滤)在已经非古典的状态下的作用。具体而言,我们选择了一个二项式状态,该状态被称为非经典的测试床,并在真空中燃烧一个孔(等效地过滤了真空状态)。要检查真空过滤的二项式状态的非经典特性,我们使用了Vogel的标准,高阶和低阶抗启发的标准,高阶次级副子光子光子统计的标准,线性熵等。研究结果表明,在这里研究的真空过滤的二型二进制状态是高度非固定的,并且该二进制型不合格,并且该进程是不概述的。

In quantum optics, nonclassical properties of various quantum states of radiation field are frequently studied. Some of those states are finite dimensional and referred to as qudits. These states are important because of their potential applications in quantum information processing. Further, nonclassical states are those which do not have any classical counterpart. Consequently, to establish quantum supremacy, we always require nonclassical state. Recently, Sivakumar and Meher have studied the nonclassical properties of the number state filtered coherent state, and shown that the number state filtering introduces nonclassical features into coherent state which is otherwise classical. This observation motivated us to investigate the role of hole burning (state filtering) on a state which is already nonclassical. Specifically, we have selected a Binomial state which is known to be nonclassical as our test bed and burnt a hole at vacuum (equivalently filtered the vacuum state). To check the nonclassical properties of vacuum filtered binomial state, we have used Vogel's criterion, criterion of higher- and lower-order antibunching, criterion of higher-order sub-Poissonian photon statistics, Linear entropy etc. The investigation results show that vacuum filtered binomial state studied here is highly nonclassical, and the hole burning process enhances the nonclassical depth.
