AI总结:

本文利用量子极值面公式研究体熵量子贡献与全息熵不等式的关系,证明体熵满足 HEC 或 MMI 时,边界熵也分别满足对应约束。

摘要:

已知具有几何对偶的量子态满足一组比一般量子系统所遵循的更严格的熵不等式。利用 Ryu-Takayanagi(RT)公式导出的允许熵集合定义了全息熵锥(Holographic Entropy Cone,HEC)。一旦通过采用量子极值面(Quantum Extremal Surface,QES)处方纳入一般量子修正,这些不等式便不再得到满足。尽管如此,QES 公式的结构使人们能够可控地研究来自体熵的量子贡献如何与 HEC 不等式相互作用。本文中,我们通过将体熵约束与边界熵不等式联系起来,开启了对这一问题的探索。特别地,我们证明,要求体熵满足 HEC,意味着边界熵也满足 HEC。此外,我们还证明,要求体熵遵守互信息一夫一妻制(monogamy of mutual information,MMI),意味着边界熵也遵守 MMI。

英文摘要:

Quantum states with geometric duals are known to satisfy a stricter set of entropy inequalities than those obeyed by general quantum systems. The set of allowed entropies derived using the Ryu-Takayanagi (RT) formula defines the Holographic Entropy Cone (HEC). These inequalities are no longer satisfied once general quantum corrections are included by employing the Quantum Extremal Surface (QES) prescription. Nevertheless, the structure of the QES formula allows for a controlled study of how quantum contributions from bulk entropies interplay with HEC inequalities. In this paper, we initiate an exploration of this problem by relating bulk entropy constraints to boundary entropy inequalities. In particular, we show that requiring the bulk entropies to satisfy the HEC implies that the boundary entropies also satisfy the HEC. Further, we also show that requiring the bulk entropies to obey monogamy of mutual information (MMI) implies the boundary entropies also obey MMI.
