论文摘要
互补性和纠缠是量子力学的基本特征，这些特征最近在试验性平等上相关，涉及量子相干性，量子的波动方面以及量子可预测性和量子纠缠，这是乘以量子的粒子方面。在本文中，我们在最初部分纠缠状态的纠缠交换中提供可及性和纠缠之间的操作联系。为此，我们表明，测量前一分密度矩阵的可预测性直接与后衡态的部分纠缠成分的概率有关。进一步进一步，我们根据互补关系分析了部分纠缠状态的纠缠交换，并表明，在铃声测量后纠缠增加的情况下，与最初准备好的状态相比，可消耗的可预测性。
Complementarity and entanglement are fundamental features of Quantum Mechanics that were recently related in triality equalities that involve quantum coherence, the wave aspect of a qubit, and quantum predictability and quantum entanglement, the particle aspect of a qubit. In this article, we give an operational connection between redictability and entanglement in entanglement swapping from initially partially entangled states. For this, we show that the predictability of the pre-measurement one-qubit density matrix is directly related to the probability of the partially entangled component of the post-measurement state. Going even further, we analyze the entanglement swapping for partially entangled states in the light of complementarity relations and show that, in the cases where the entanglement increases after a Bell-basis measurement, the predictability is consumed when compared to the initially prepared state.
