高维对象一夫一妻制不等式的破坏

Violation of monogamy inequality for higher-dimensional objects

Yong-Cheng Ou

摘要:

研究了量子态和高维物体的两体量子纠缠。我们分析的可能性违反一夫一妻制的不平等,介绍了由Coffman,Kundu和Wootters,一些系统组成的这样的对象。给出了一个三重态完全反对称的显式反例。由于三纠缠已被证实是量子比特系统的一种自然的纠缠度量,我们的结果表明,三纠缠不再是具有三个量子比特或更高维物体的纠缠的合理度量。

英文摘要:

Bipartite quantum entanglement for qutrits and higher-dimensional objects is considered. We analyze the possibility of violation of monogamy inequality, introduced by Coffman, Kundu, and Wootters, for some systems composed of such objects. An explicit counterexample with a three-qutrit totally antisymmetric state is presented. Since three-tangle has been confirmed to be a natural measure of entanglement for qubit systems, our result shows that the three-tangle is no longer a legitimate measure of entanglement for states with three qutrits or higher dimensional objects.
