Tóm tắt

The novel quantum dialogue (QD) protocol by using the three-qubit GHZ states (Quantum Inf Process (2019) 18: 37) is cryptanalyzed. It is found that there is the information leakage problem in this QD protocol. To be specific, half information of the secret messages exchanged is leaked out unconsciously. Afterwards, a way to improve this protocol is discussed.
