Abstract

Recently, Pan put forward a quantum dialogue (QD) scheme based on entanglement swapping and Hadamard operation via cavity QED (Int J Theor Phys, 58(2019)1017), and claimed that this scheme is secure. This paper first points out that it runs the risk of information leakage, and then suggests an improvement to remedy this security loophole.
