“…To fit into the operational mobile communication framework and allow telecom companies to provide secure communication, a controlled bidirectional QSDC protocol based on the properties of GHZ-states was invented and applied in mobile networks [454]. Some techniques of the network layer, such as quantum multiple access techniques and routing have also been considered in multi-user QSDC networks [455], [456]. Indeed, we may view the overall communication networks as a hybrid one relying on a quantum and a classical channel, where the confidential messages are transmitted directly over the quantum channels and the classical channels simply assist in eavesdropping detection.…”

Communication security has to evolve to a higher plane in the face of the threat from the massive computing power of the emerging quantum computers. Quantum secure direct communication (QSDC) constitutes a promising branch of quantum communication, which is provably secure and overcomes the threat of quantum computing, whilst conveying secret messages directly via the quantum channel. In this survey, we highlight the motivation and the status of QSDC research with special emphasis on its theoretical basis and experimental verification. We will detail the associated point-to-point communication protocols and show how information is protected and transmitted. Finally, we discuss the open challenges as well as the future trends of QSDC networks, emphasizing again that QSDC is not a pure quantum key distribution (QKD) protocol, but a fully-fledged secure communication scheme.
