DOI: 10.1007/s10773-019-04080-0
Abstract: Recently, Ye et al. (Int. J. Theor. Phys. 56, 1517–1529, 2017) proposed a quantum private comparison (QPC) protocol based on five-qubit entanglement state. Two parties can verify that their secret information is equal or not… 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: 10.1088/1402-4896/aad0fa
Abstract: Since unconditionally secure quantum two-party computations are known to be impossible, most existing quantum private comparison (QPC) protocols adopted a third party. Recently, we proposed a QPC protocol which involves two parties only, and showed… read more here.
