摘要:Abstract(#br)Quantum private comparison (QPC) allows at least two participants who do not trust each other to compare whether their secret data are the same while maintaining data privacy, in which the security is based on the principles of quantum mechanics. In this paper, we ...

摘要:As a typical quantum cryptographic task between distrustful participants, quantum private comparison (QPC) has attracted a lot of attention in recent years. Here we propose two QPC protocols employing single-photon interference, a typical and interesting technology for quantum co...

摘要:In this paper, a two-party quantum private comparison (QPC) protocol is proposed by using five-qubit entangled states as the quantum resource. The proposed protocol needs the help from a semi-honest third party (TP), who is allowed to misbehave on his own but not allowed to consp...

摘要:A two-party quantum private comparison (QPC) protocol is constructed with χ -type entangled states in this paper. The proposed protocol employs a semi-honest third party (TP) that is allowed to misbehave on his own but cannot conspire with the adversary. The proposed protocol n...

摘要:In this paper, a novel multi-party quantum private comparison protocol with a semi-honest third party (TP) is proposed based on the entanglement swapping of d -level cat states and d -level Bell states. Here, TP is allowed to misbehave on his own, but will not conspire with a...

摘要:Abstract(#br)We propose an efficient quantum protocol for comparing the equal information with the help of a semi-honest third party (TP). Our protocol utilizes the triplet W states and the single-particle measurement. A precise proof of security of the protocol is presented. The...
