论文摘要

我们在Rényi熵与概率分布的巧合索引之间构建了不平等,基于我们,我们获得了一般对称信息的一般信息完整的正面操作员评估措施(SIC-POVM)的依赖性状态依赖性熵不确定性关系,并在有限的减小系统上获得了相互无公正的测量(MUM)。我们表明,对于充分混合的状态,我们对一般的SIC-POVM和妈妈的不确定性关系可能很紧,此外,与数值最佳结果的比较是通过信息图进行的。

We construct inequalities between Rényi entropy and the indexes of coincidence of probability distributions, based on which we obtain improved state-dependent entropic uncertainty relations for general symmetric informationally complete positive operator-valued measures (SIC-POVM) and mutually unbiased measurements (MUM) on finite dimensional systems. We show that our uncertainty relations for general SIC-POVMs and MUMs can be tight for sufficiently mixed states, and moreover, comparisons to the numerically optimal results are made via information diagrams.
