China Telecom China Telecom Quantum Group released the world's first distributed cryptographic system integrating QKD and PQC.

On the 14th, it was learned from China Telecom that its Quantum Group recently released the world's first distributed cryptographic system integrating QKD and PQC. This system innovatively merges QKD and PQC technologies to provide users with end-to-end resistant quantum computing key distribution and key lifecycle management, and has commercial capabilities. At the same time, the world's first cross-domain quantum secure phone system based on integrated QKD and PQC successfully connected over 1000 kilometers. Currently, the system architecture has undergone multiple scenario verifications, and with the official launch of the current network, it signifies that China's integrated cryptographic system based on "QKD+PQC" has officially entered a new stage of scalable commercial use, and also heralds the systematic technological breakthrough of the new generation of quantum security infrastructure.
