论文摘要
我们将双目标量子状态的运动学视为可观察量的数量，特别是子系统的Bloch载体。在检查一对两级系统的最简单情况时，非古典相关的存在与由Bloch矢量的相关矩阵的奇异值分解产生的两个碱基的手性之间存在着显着的联系。我们研究了这种效果的量子力学及其与其他方法量化系统非古典行为所施加的限制。
We consider the kinematics of bi-partite quantum states as determined by observable quantities, in particular the Bloch vectors of the subsystems. In examining the simplest case of a pair of two-level systems, there is a remarkable connection between the presence of non-classical correlations and the chirality of the two bases generated by the singular value decomposition of the correlation matrix of the Bloch vectors. We investigate the limits imposed by quantum mechanics of this effect and it relationship with other methods on quantifying the system's non-classical behaviour.
