文摘

Existing classical post-processing (CPP) schemes for quantum key distribution (QKD)-based quantum private queries (QPQs) including the \(kN\rightarrow N\), \(N\rightarrow N\), and \(rM\rightarrow N\) ones have been found imperfect in terms of communication efficiency and security. In this paper, we propose a novel CPP scheme for QKD-based QPQs. The proposed CPP scheme reduces the communication complexity and improves the security of QKD-based QPQ protocols largely. Furthermore, the proposed CPP scheme can provide a multi-bit query efficiently.KeywordsQuantum private queryQuantum key distributionCommunication complexitySecurity
