For any $n$-bit boolean function $f$, we show that the randomized communication complexity of the composed function $f\circ g^n$, where $g$ is an index gadget, is characterized by the randomized decision tree complexity of $f$. In particular, this means that many query complexity separations involving randomized models (e.g., classical vs. quantum) automatically imply analogous separations in communication complexity.

BPP的查询到通信提升

SIAM Journal on Computing,第49卷,第4期,第FOCS17-441-FOCS17-461页,2020年1月。
对于任何$ n $位布尔函数$ f $,我们证明了组合函数$ f \的随机通信复杂度。 circ g ^ n $,其中$ g $是索引小工具,其特征在于$ f $的随机决策树复杂度。特别是,这意味着涉及随机模型(例如经典模型与量子模型)的许多查询复杂性分离会自动暗示通信复杂性的类似分离。
