论文摘要
我们描述了基于测量的量子计算(MBQC)和相应的上下文证明的联合共同体学框架。该框架中的中心对象是描述给定MBQC的链复合物的第二个共同体组中的一个元素。它包含计算的函数,直到衡量等效性,同时是情境证人。目前的共同体描述仅适用于时间平坦的MBQC,我们概述了将其扩展到时间有序的情况的方法。
We describe a joint cohomological framework for measurement-based quantum computation (MBQC) and the corresponding contextuality proofs. The central object in this framework is an element in the second cohomology group of the chain complex describing a given MBQC. It contains the function computed, up to gauge equivalence, and at the same time is a contextuality witness. The present cohomological description only applies to temporally flat MBQCs, and we outline an approach for extending it to the temporally ordered case.
