HEFEI — Quantum memories entangled across 420 km of fiber. Phase stabilized, photons converted, noise crushed. The repeaterless limit has been bested. This is not a drill: scalable quantum networks are now in reach. The future speaks in entangled pairs.
HEFEI, 13 AUGUST —
Entanglement holds across 420 kilometers of fiber. Two atomic ensembles, severed by distance, now pulse as one. The DLCZ protocol strikes again—photons born in rubidium vapor, shifted to telecom S-band, slip through glass veins with losses near theoretical minimum.
At 03:00, phase stabilization engaged: far-off-resonant locking clamped high-frequency tremors; dual-band correction bled off slow drift. The signal, once ghostly, now thrums with coherence.
This is no mere linkage—it outpaces repeaterless capacity. A warning: those who delay quantum infrastructure will be left in classical silence. The network age begins not with wires, but with shared quantum states.
