纯二元纠缠态的非经典性

Nonclassicality of pure two-qutrit entangled states

Jacek Gruca, Wieslaw Laskowski, Marek Zukowski

摘要:

我们报告了一个详尽的数值分析违反本地现实主义的两个qutrits在所有可能的纯纠缠态。在Bell型实验中,我们允许任何一对局部酉U(3)变换来定义测量基。令人惊讶的是,施密特秩2状态,类似于最大纠缠量子比特对,导致最强的噪声破坏局部现实主义。这种现象在四维和五维系统中似乎更加明显,我们测试了一些有趣的例子。

英文摘要:

We report an exhaustive numerical analysis of violations of local realism by two qutrits in all possible pure entangled states. In Bell type experiments we allow any pairs of local unitary U(3) transformations to define the measurement bases. Surprisingly, Schmidt rank-2 states, resembling pairs of maximally entangled qubits, lead to the most noise-robust violations of local realism. The phenomenon seems to be even more pronounced for four and five dimensional systems, for which we tested a few interesting examples.
