论文摘要
在最近的一项工作中[S.哮喘。新的物理学杂志24.5（2022）：053026]，我们显示了单个逻辑量子量子量子相干性的多Qualbit Systems中不同非经典相关性的相互关系。在这项工作中，我们将其推广到高维系统。为此，我们从构成物理Qudits和物理CV系统方面采取了逻辑Qudits和逻辑连续变量（CV）系统的不同选择。此后，我们显示了连贯性的条件（在逻辑Qudits和逻辑CV系统中）与非局部性和纠缠条件（在其基本组成量和CV系统中）之间的互惠。这表明单个非经典性条件检测到不同物理系统中不同类型的非经典性。因此，它反映了属于非相同维度希尔伯特空间的状态的不同非经典特征的相互关系。
In a recent work [S. Asthana. New Journal of Physics 24.5 (2022): 053026], we have shown the interrelation of different nonclassical correlations in multiqubit systems with quantum coherence in a single logical qubit. In this work, we generalize it to higher-dimensional systems. For this, we take different choices of logical qudits and logical continuous-variable (cv) systems in terms of their constituent physical qudits and physical cv systems. Thereafter, we show reciprocity between conditions for coherence (in logical qudits and logical cv systems) and conditions for nonlocality and entanglement (in their underlying constituent qudits and cv systems). This shows that a single nonclassicality condition detects different types of nonclassicalities in different physical systems. Thereby, it reflects the interrelations of different nonclassical features of states belonging to Hilbert spaces of nonidentical dimensions.
