DOI: 10.1007/s10773-020-04485-2
Abstract: As we know, if a quantum communication protocol has the information leakage problem, it is an insecure protocol, so we should carefully design the protocol to avoid the information leakage problem. Unfortunately, we find this… read more here.

DOI: 10.1007/s10773-021-04895-w
Abstract: In this paper, a controlled quantum dialogue protocol is designed based on five-qubit entangled states. One five-qubit entangled state can be used to exchange one communicant’s two private bits with the other communicant’s two private… read more here.

DOI: 10.1007/s11128-016-1461-2
Abstract: A new quantum dialogue protocol is designed by using the continuous-variable two-mode squeezed vacuum states due to its entanglement property. The two communication parties encode their own secret information into the entangled optical modes with… read more here.
