| 中文摘要: |
| 研究了量子信息理论中无限维两体量子态的可分性鲁棒和纠缠鲁棒问题。利用无限维两体量子系统态的Concurrence纠缠度以及可分态的边缘态的概念，讨论了无限维两体量子态的可分性鲁棒和纠缠鲁棒的定义。得到了可分性鲁棒以及纠缠鲁棒的若干基本性质，推广了有限维两体量子态的相应结果，获得了无限维两体量子系统态的可分性鲁棒和纠缠鲁棒分别为零的等价条件。 |
| 英文摘要: |
| The separability robustness and entanglement robustness for states in infinite dimensional quantum systems in quantum information theory were studied. Using Concurrence entanglement measure and edge states of separable states in infinite dimensional quantum systems, the concepts of separability robustness and entanglement robustness for states in infinite dimensional quantum systems was discussed. Some properties of separability robustness and entanglement robustness for infinite dimensional quantum states were obtained. Furthermore, these results generalize the corresponding results of bipartite finite dimensional quantum systems. We obtain some equivalents conditions of zero separability robustness and entanglement robustness. |
