The development of quantum technology has been a key focus of China in recent years. Characterized by its no-cloning theorem and its uncertainty, the technology plays an important role in ensuring network information security.

On April 1, Xiongan New Area in north China's Hebei Province, which has been designed to become a smart city, celebrated the fifth anniversary of its establishment.

CGTN reporter Guo Meiping sat down with Wang Ti, director of Quantum Communication Technology and Application Research Laboratory (Application Demonstration Center) of Xiongan, and CTO of China Unicom Smart City Research Institute, to talk about how quantum technology can ensure communication safety in the city and the rest of China.
