| 摘 要： | 利用相干度量的定义式和三维X型态的密度矩阵对3类相干度量的解析表达式进行了研究,并给出了具体解析表达式.这3类相干度量分别为基于范数的相干度量(l1范数相干、 lp范数相干(p>1)、 α - 亲和度相干)、基于熵的相干度量(相对熵相干、Tsallis - α相对熵相干、 Rényi - α相对熵相干)和基于斜信息的相干度量.该研究结果可为在不同相干度量下讨论量子态的权衡关系、不确定性关系以及序关系提供参考.

| Abstract: | Using the definition of coherence measure and the density matrix of three - dimensional X- type state, the analytical expressions of three kinds of coherence measures are studied and given.These three kinds of coherence measures are norm - based coherence measures, which are based on norms(l1 - norm coherence measure, lp - norm coherence measure(p > 1), Rényi - α relative entropy coherence), coherence based on entropy(relative entropy coherence measure, α - affinity coherence measure, Tsallis - α relative entropy coherence)and skew information coherence measure.The research results can provide a reference for discussing the trade - off, uncertainty and order relations of quantum states under different coherence measures. |
