USTC achieves record quantum frequency conversion efficiency

By PulseAugur Editorial · [1 sources] ·

Researchers at the University of Science and Technology of China have achieved a new record in quantum frequency conversion, reaching 28.8% end-to-end efficiency. This breakthrough allows for the connection of ultraviolet trapped-ion quantum memories to standard telecommunications fiber networks. The team successfully reduced pump noise to 35 counts per second, a critical step for practical quantum communication systems. AI

IMPACT Enables more robust and longer-distance quantum communication networks by linking ion-based quantum memories to existing fiber infrastructure.
