Quantum secure direct communication (QSDC) has gained significant attention due to its use of quantum physical principles to guarantee unconditional security. This article provides a brief overview of QSDC, discussing its evolution, security proof, performance improvement techniques, practical implementation, and future directions.
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. Finally, we discuss the future directions of QSDC.
