A Unitary Operator Construction Solution Based on Pauli Group for Maximal Dense Coding
Wenjie Liu, Junxiu Chen, Wenbin Yu +2
Quantum dense coding plays an important role in quantum cryptography communication, and how to select a set of appropriate unitary operators to encode message is the primary work i…
Quantum forgery attacks on COPA,AES-COPA and marble authenticated encryption algorithms
Yinsong Xu, Wenjie Liu, Wenbin Yu
The classic forgery attacks on COPA, AES-COPA and Marble authenticated encryption algorithms need to query about 2^(n/2) times, and their success probability is not high. To solve…
A Unitary Weights Based One-Iteration Quantum Perceptron Algorithm for Non-Ideal Training Sets
Wenjie Liu, Peipei Gao, Yuxiang Wang +2
In order to solve the problem of non-ideal training sets (i.e., the less-complete or over-complete sets) and implement one-iteration learning, a novel efficient quantum perceptron…
An Efficient and Secure Arbitrary N-Party Quantum Key Agreement Protocol Using Bell States
Wen-Jie Liu, Yong Xu, Ching-Nung Yang +2
Two quantum key agreement protocols using Bell states and Bell measurement were recently proposed by Shukla et al.(Quantum Inf. Process. 13(11), 2391-2405, 2014). However, Zhu et a…
