Hidden Tiangong3 Link Cuts Space Science And Technology 60%
Tiangong-3 will enable secure, real-time quantum communication between Earth and orbit, thanks to its integrated quantum key distribution payload. Early uplink trials from Qinzhou proved entangled photon transmission over 1200 km, setting a new benchmark for space-based cryptography. In 2024, China completed 1200 km of entangled photon uplink testing with
