Quantum contextuality plays a significant role in supporting quantum computation and quantum information theory. The key tools for this are the Kochen-Specker and non-Kochen-Specker contextual sets. Traditionally, their representation has been predominantly operator-based, mainly focusing on specific constructs in dimensions ranging from three to eight. However, nearly all of these constructs can be represented as low-dimensional hypergraphs. This study demonstrates how to generate contextual hypergraphs in any dimension using various methods, particularly those that do not scale in complexity with increasing dimensions. Furthermore, we introduce innovative examples of hypergraphs extending to dimension 32. Our methodology reveals the intricate structural properties of hypergraphs, enabling precise quantifications of contextuality. Additionally, we investigate several promising applications of hypergraphs in quantum communication and quantum computation, paving the way for future breakthroughs in the field.
量子语境性在支持量子计算和量子信息理论方面发挥着重要作用。为此的关键工具是科亨 - 施佩克尔(Kochen - Specker)语境集和非科亨 - 施佩克尔语境集。传统上,它们的表示主要基于算子,主要关注维度从三到八的特定结构。然而,几乎所有这些结构都可以表示为低维超图。本研究展示了如何使用各种方法在任何维度生成语境超图,特别是那些复杂度不会随维度增加而扩展的方法。此外,我们引入了扩展到32维的超图的创新示例。我们的方法揭示了超图复杂的结构特性,能够对语境性进行精确量化。此外,我们研究了超图在量子通信和量子计算中的几个有前景的应用,为该领域未来的突破铺平了道路。
