For the first time, physicists transmitted quantum information between two quantum chips over optical fiber.

A quantum whisper was turned into a beam of light, ran a kilometer through optical fiber, and was heard again in a second refrigerator. The signal didn't degrade. The bridge between quantum islands worked. Now all that's left is to weave the network.

🎯 Light travels a kilometer in 3 microseconds—faster than the blink of an eye.

🎬 This quantum bridge is like the ansible from science fiction: it connects not planets, but quantum processors.
