摘要:

量子不确定关系通常针对一对不相容可观测量进行分析,但其概念本身可自然拓展至多于两个可观测量的场景。本研究推导出三方量子存储辅助熵不确定关系,证明这些关系的下界包含三项,分别取决于可观测量的互补性、条件冯·诺依曼熵、Holevo量与互信息。文中还分析了这些不等式的饱和条件。

英文摘要:

Quantum uncertainty relations are typically analyzed for a pair of incompatible observables, however, the concept per se naturally extends to situations of more than two observables. In this work, we obtain tripartite quantum memory-assisted entropic uncertainty relations and show that the lower bounds of these relations have three terms that depend on the complementarity of the observables, the conditional von-Neumann entropies, the Holevo quantities, and the mutual information. The saturation of these inequalities is analyzed.
