Comment on quantum private comparison protocols with a semi-honest third party
TL;DR: This paper studies the security of previous QPC protocols with a semi-honest third party (TP) from the viewpoint of secure multi-party computation and shows that the assumption of a semi -honest TP is unreasonable.

Novel multiparty quantum key agreement protocol with GHZ states
TL;DR: This paper proposes a novel three-party QKA protocol, which is designed by using Greenberger–Horne–Zeilinger (GHZ) states, and shows that the new scheme is secure and fair to every participant.

A Protocol for the Quantum Private Comparison of Equality with χ-Type State
TL;DR: A new quantum protocol for comparing the equal information with the help of a semi-honest third party (TP) is presented, different from previous protocols, that utilizes the four-particle χ-type states as the information carriers.
Journal ArticleDOI
Efficient quantum private comparison employing single photons and collective detection
TL;DR: Two efficient quantum private comparison protocols are proposed, employing single photons and collective detection to compare the equivalence of information with the help of a semi-honest third party.

TL;DR: An unknown quantum state \ensuremath{\Vert}\ensure Math{\varphi}〉 can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations.

Quantum cryptography based on Bell's theorem.
TL;DR: Practical application of the generalized Bells theorem in the so-called key distribution process in cryptography is reported, based on the Bohms version of the Einstein-Podolsky-Rosen gedanken experiment andBells theorem is used to test for eavesdropping.

Polynomial-Time Algorithms for Prime Factorization and Discrete Logarithms on a Quantum Computer
TL;DR: In this paper, the authors considered factoring integers and finding discrete logarithms on a quantum computer and gave an efficient randomized algorithm for these two problems, which takes a number of steps polynomial in the input size of the integer to be factored.
Journal ArticleDOI
Quantum Cryptography
TL;DR: The author revealed that quantum teleportation as “Quantum one-time-pad” had changed from a “classical teleportation” to an “optical amplification, privacy amplification and quantum secret growing” situation.
Journal ArticleDOI
Experimental quantum teleportation
TL;DR: In this article, the authors demonstrated the feasibility of quantum teleportation over arbitrary distances of the state of a quantum system by using a measurement such that the second photon of the entangled pair acquires the polarization of the initial photon.
