• Authors: Xiang-Jie Li, Dong Pan, Gui-Lu Long, and Lajos Hanzo
• Abstract summary: Quantum secure direct communication (QSDC) has attracted a lot of attention, which exploits deep-rooted quantum physical principles to guarantee unconditional security of communication in the face of eavesdropping. We first briefly review the fundamentals of QSDC, and then present its evolution, including its security proof, its performance improvement techniques, and practical implementation.
