This paper concerns the analysis of large quantum states. It is a notoriously difficult problem to quantify separability of quantum states, and for large quantum states, it is unfeasible. Here we posit that when quantum states are large, we can deduce reasonable expectations for the complex structure of non-classical multipartite correlations with surprisingly little information about the state. We show, with pegagogical examples, how known results from combinatorics can be used to reveal the expected structure of various correlations hidden in the ensemble described by a state.
本文关注的是大量子态的分析。量子态的可分性量化是一个极其困难的问题，对于大量子态而言，这是不可行的。在此我们假定，当量子态很大时，我们能够以关于该态少得惊人的信息推断出对非经典多体关联复杂结构的合理预期。我们通过示例说明，组合数学中的已知结果如何能够用于揭示隐藏在由一个态所描述的系综中的各种关联的预期结构。
