重新包装的全息熵关系

Holographic Entropy Relations Repackaged

Temple He, Matthew Headrick, Veronika E. Hubeny

摘要:

我们探索全息熵关系的结构(与“信息量”的线性组合的纠缠熵的空间子分区的几何体对偶的CFT状态)。这样的熵关系可以用多种方式来重塑,其中一些具有显著的优势。出于已经注意到的简化熵的关系时,重铸的多部信息,我们探索额外的简化重铸时,在一个新的基础上,我们称之为K-基础,从完美的张量结构。对于基本信息量,这样的重铸是令人惊讶的紧凑,部分原因是有趣的事实,即与完美张量相关的熵向量实际上是全息熵锥(以及完整的量子熵锥)中的极端射线。更重要的是,我们证明了所有的全息熵不等式都有正系数时,表示在K-基,潜在的关键优势,熵基础或多部信息基础。

英文摘要:

We explore the structure of holographic entropy relations (associated with 'information quantities' given by a linear combination of entanglement entropies of spatial sub-partitions of a CFT state with geometric bulk dual). Such entropy relations can be recast in multiple ways, some of which have significant advantages. Motivated by the already-noted simplification of entropy relations when recast in terms of multipartite information, we explore additional simplifications when recast in a new basis, which we dub the K-basis, constructed from perfect tensor structures. For the fundamental information quantities such a recasting is surprisingly compact, in part due to the interesting fact that entropy vectors associated to perfect tensors are in fact extreme rays in the holographic entropy cone (as well as the full quantum entropy cone). More importantly, we prove that all holographic entropy inequalities have positive coefficients when expressed in the K-basis, underlying the key advantage over the entropy basis or the multipartite information basis.
