This experiment validates the viability of using existing commercial fiber optic infrastructure for long-distance quantum communication by demonstrating robust entanglement over 62 kilometers above ground. The success relies on active stabilization techniques that correct environmental distortions in real-time, proving practical protocols can function outside controlled laboratory settings. This milestone significantly advances the roadmap for deploying scalable, real-world quantum networks using current cable systems rather than requiring specialized underground infrastructure.
NIST sends ‘spooky’ quantum link from Gaithersburg to College Park
NIST sent entangled photons 62 kilometers, from its Gaithersburg campus to the University of Maryland in College Park, proving quantum states can survive real-world fiber.
Entangled photons successfully traveled 62 kilometers (about 38.5 miles) through commercial fiber optic cables stretching from the National Institute of Standards and Technology (NIST) in Gaithersburg to the University of Maryland in College Park. This achievement, reported in the Journal of Optical Communications and Networking, demonstrates the survival of fragile quantum entanglement in real-world conditions, a key step toward building a quantum network. NIST physicist Oliver Slattery described the…
