Generalised Mermin-type non-locality arguments

Stefano Gogioso, William Zeng

AI总结:

本文推广Mermin型论证至GHZ态,给出非定域性的精确群论条件,产生新的量子可实现全对无论证层级,并应用于HBB秘密共享方案的扩展,证明采用字符串图语言,适用于更广理论。

摘要:

我们广泛推广了关于GHZ态的Mermin型论证,并给出了实现非定域性的精确群论条件。我们的结果在量子基础中具有重要意义,它们产生了一个新的量子可实现的全对无(All-vs-Nothing)论证层级。这些结果对量子协议也具有意义,它们直接应用于Hillery、Bužek和Berthiaume(HBB)提出的混合量子-经典秘密共享方案的非平凡扩展。我们的证明在dagger紧致范畴的字符串图图形语言中进行,其有效性超越了量子理论,适用于任何具有相关代数结构的理论。

英文摘要:

We broadly generalise Mermin-type arguments on GHZ states, and we provide exact group-theoretic conditions for non-locality to be achieved. Our results are of interest in quantum foundations, where they yield a new hierarchy of quantum-realisable All-vs-Nothing arguments. They are also of interest to quantum protocols, where they find immediate application to a non-trivial extension of the hybrid quantum-classical secret sharing scheme of Hillery, Bužek and Berthiaume (HBB). Our proofs are carried out in the graphical language of string diagrams for dagger compact categories, and their validity extends beyond quantum theory to any theory featuring the relevant algebraic structures.
