AI 中文摘要
我们研究量子 Merlin - Arthur(QMA)查询和通信复杂性中的批量验证,目标是了解验证布尔函数\(f\)的\(m\)个副本所需资源如何依赖于\(m\)。我们给出一种通用技术,用于根据近似度证明批量验证函数\(f\)所需见证查询权衡的下限。将此技术应用于显式的析取范式(DNF)公式族\(f\),表明即使在批量验证\(f\)的基线方法的见证长度上节省常数因子,也需要查询成本大幅多项式增加。我们还获得了一次读取合取范式(CNF)公式的 QMA 查询复杂性以及满射性和\(k\)元互异性函数的新下限。我们的下限还可提升以给出这些结果的通信类似物。
英文摘要
We study batch verification in QMA query and communication complexity, where the goal is to understand how the resources needed to verify $m$ copies of a Boolean function $f$ depend on $m$. We give a general technique for proving lower bounds on the witness-query tradeoff needed to batch verify a function $f$ in terms of its approximate degree. Applying this technique to an explicit family of DNF formulas $f$, we show that attempting to save even a constant factor on the witness length of the baseline approach to batch verifying $f$ necessitates a large polynomial increase in the query cost. We also obtain new lower bounds on the QMA query complexity of read-once CNF formulas and on the surjectivity and $k$-element distinctness functions. Our lower bounds also lift to give communication analogs of these results.
