报告摘要
Quantum secure direct communication (QSDC) is one branch of quantum cryptography. In QSDC, secret message is sent directly over a quantum channel. QSDC has changed the infra-structure of secure communication. QSDC is also a powerful basic quantum communication primitive to build other quantum communication protocols. In this talk, I will briefly introduce the basic ideas of QSDC, some typical QSDC protocols. In recent years, studies of QSDC in a noisy and lossy environment has achieved rapid progress. Security analysis and robust coding has been developed, and quantum-memory-free QSDC protocol has been designed, which circumvent one biggest difficulty in practical QSDC. Now a prototype setup has been completed with a distance of 10 km in commercial fiber, working at a secure rate of 4.6 kbps. Extensive researches on QSDC are under way around the world, including MIT, Rochester, NIST, Oakridge National Laboratory, and so on. Future perspective is also given toward the end of the talk.
