群体成员关系的单向通信复杂性

The One-Way Communication Complexity of Group Membership

Scott Aaronson, François Le Gall, Alexander Russell, Seiichiro Tani

摘要:

研究了与量子计算基本问题密切相关的经典问题--子群成员问题的单向通信复杂性。在这里,Alice接收有限群$G$的子群$H$作为输入; Bob接收元素$x \in G$。Alice被允许向Bob发送单个消息,之后他必须决定他的输入$x$是否是$H$的元素。在有界误差下,我们证明了该问题的经典通信复杂性的上界:(1)如果子群$H$是正规的,则该问题可以用$O(\log |G|)$通信来解决;(2)该问题可以用$O(d_{\max} \cdot \log |G|)$通信来解决,其中$d_{\max}$是$G$的不可约复表示的维数的最大值;(3)对于任何不划分$|G|$的素数$p$,该问题可以用$O(d_{\max} \cdot \log p)$通信来解决,其中$d_{\max}$是$G$的不可约$\F_p$ -表示的维数的最大值。

英文摘要:

This paper studies the one-way communication complexity of the subgroup membership problem, a classical problem closely related to basic questions in quantum computing. Here Alice receives, as input, a subgroup $H$ of a finite group $G$; Bob receives an element $x \in G$. Alice is permitted to send a single message to Bob, after which he must decide if his input $x$ is an element of $H$. We prove the following upper bounds on the classical communication complexity of this problem in the bounded-error setting: (1) The problem can be solved with $O(\log |G|)$ communication, provided the subgroup $H$ is normal; (2) The problem can be solved with $O(d_{\max} \cdot \log |G|)$ communication, where $d_{\max}$ is the maximum of the dimensions of the irreducible complex representations of $G$; (3) For any prime $p$ not dividing $|G|$, the problem can be solved with $O(d_{\max} \cdot \log p)$ communication, where $d_{\max}$ is the maximum of the dimensions of the irreducible $\F_p$-representations of $G$.
