论文摘要
通过在量子zeno效应下使用开放式两种原子系统的伪模论来研究纠缠证人和熵不确定性。结果表明，只有当两个光谱与原子结合在一起时，纠缠证人的时间才能延长，并且可以减少熵不确定性的下限，并且可以多次见证纠缠。我们还通过非马克维亚语给出了相应的物理解释。 Zeno效应不仅可以非常有效地延长纠缠见证人的时间并减少熵不确定性的下限，而且还可以大大增加纠缠证人的时间并降低证人的纠缠价值。
The entanglement witness and the entropy uncertainty are investigated by using the pseudomode theory for the open two-atom system under the quantum Zeno effect. The results show that, only when the two spectrums satisfy strong coupling with the atom, the time of entanglement witness can be prolonged and the lower bound of the entropic uncertainty can be reduced, and the entanglement can be witnessed many times. We also gave the corresponding physical explanation by the non-Markovianity. The Zeno effect not only can very effectively prolong the time of entanglement witness and reduce the lower bound of the entropy uncertainty, but also can greatly enhance the time of entanglement witness and reduce the entanglement value of witness.
