摘要
It is found that there is the information leakage problem in the secure quantum dialogue (QD) protocol via cavity QED (Ye, Int J Theor Phys 54(3): 772-779 2015). To be specific, one out of the four bits about the secret messages is leaked out. Finally, an improved QD protocol without information leakage is put forward. It is sincerely hoped that researchers pay more attention to the information leakage problem in quantum secure communication to design truly secure protocols.
