基于测量的量子计算中的上同调和上下文的代数结构

Cohomology and the Algebraic Structure of Contextuality in Measurement Based Quantum Computation

Sivert Aasnæss

摘要:

好的,Roberts,Bartlett和Raussendorf最近介绍了一种新的上同调方法,用于基于测量的量子计算中的上下文。我们给出了一个抽象的描述,他们的障碍和代数结构,它利用,使用层理论框架的阿布拉姆斯基和勃兰登堡。在这一水平的一般性,我们对比他们的方法,以切赫上同调障碍的阿布拉姆斯基,曼斯菲尔德和巴博萨,并给出一个直接的证明,切赫上同调至少是强大的。

英文摘要:

Okay, Roberts, Bartlett and Raussendorf recently introduced a new cohomological approach to contextuality in measurement based quantum computation. We give an abstract description of their obstruction and the algebraic structure it exploits, using the sheaf theoretic framework of Abramsky and Brandenburger. At this level of generality we contrast their approach to the Cech cohomology obstruction of Abramsky, Mansfield and Barbosa and give a direct proof that Cech cohomology is at least as powerful.
