上下文量子计算的上同调框架

Cohomological framework for contextual quantum computations

Robert Raussendorf

摘要:

我们描述了一个基于测量的量子计算的上同调框架,其中对称性起着核心作用。其中,关于计算输出的基本信息包含在拓扑不变量中,即两个上同调群的元素。其中一个不变量适用于确定性情况,另一个适用于一般概率情况。同样的不变量也以上下文的形式见证了量子性。结果,它们产生了量子计算的基本代数结构。

英文摘要:

We describe a cohomological framework for measurement based quantum computation, in which symmetry plays a central role. Therein, the essential information about the computational output is contained in topological invariants, namely elements of two cohomology groups. One of those invariants applies to the deterministic case, and the other to the general probabilistic case. The same invariants also witness quantumness in the form of contextuality. In result, they give rise to fundamental algebraic structures underlying quantum computation.
