DOI: 10.1007/s10773-020-04691-y
Abstract: Recently, Tian et al. proposed a multi-user quantum private query protocol. The protocol realizes the function of n users querying the database at the same time, which can well protect the privacy of users and… read more here.

DOI: 10.1007/s11128-017-1518-x
Abstract: In a recent paper (Quantum Inf Process 13:805–813, 2014), a flexible quantum private query (QPQ) protocol based on B92 protocol is presented. Here we point out that the B92-based QPQ protocol is insecure in database… read more here.

DOI: 10.1007/s11128-020-02732-3
Abstract: Quantum private query (QPQ) is a kind of secure information retrieve protocol, in which both user and database privacy can be protected. Previous QPQ protocols generally consider one user retrieving and need to be performed… read more here.

DOI: 10.1142/s0217732319501967
Abstract: Quantum private query (QPQ) is a cryptographic application that protects the privacy of both users and databases while querying the database secretly. In most existing QPQ protocols, the protection of user privacy can only be… read more here.

Two quantum private query protocols based on Bell states and single photons
Sign Up to like & getrecommendations! Published in 2021 at "Modern Physics Letters A"
DOI: 10.1142/s021773232150005x
Abstract: This paper proposes two quantum privacy query protocols. In the single vector sub-privacy query of protocol 1, it is proposed for the first time to distinguish different measurement results by publ... read more here.
