Quantum-Safe Edge Computing Nodes Deployed at 5G Base Stations: End-to-End Quantum Encryption Reaches the Last Mile
Huawei and the Chinese Academy of Sciences jointly deployed the QuantumEdge quantum security module at 2,000 5G base stations in Shenzhen, enabling quantum key distribution from base station to terminal.
On August 11, 2028, Huawei and the Chinese Academy of Sciences jointly announced that their QuantumEdge quantum security edge computing module has been deployed at 2,000 5G base stations in Shenzhen.
QuantumEdge is a compact quantum key distribution (QKD) module integrated into 5G base stations, enabling quantum-encrypted channels between base stations and user terminals. Unlike previous QKD systems requiring dedicated fiber optic lines, QuantumEdge carries quantum keys within the 5G signal itself, requiring no additional infrastructure.
Huawei's chief quantum communications scientist said QuantumEdge's deployment brings quantum-level security to "the last mile" for the first time. Currently supported devices include the Huawei Mate 70 series and select enterprise routers.
