World’s first quantum secure direct communication system

A Chinese research team has implemented the world’s first quantum secure direct communication (QSDC) system. The breakthrough provides a promising solution to counter threats in the area of communication security.

Beijing Academy of Quantum Information Sciences revealed at the 2020 ZGC Forum on Saturday that they have implemented the world’s first QSDC system.

The present system can operate with a communication rate of 4kb/s at a distance of 10 kilometers, bringing QSDC further toward practical applications.
