The National Institute of Standards and Technology says it has shown that “spooky” particles can transit the DC suburbs, a result it frames as a step toward a quantum network.
The core significance of the experiment is not just distance or location, but durability: according to NIST, the achievement shows that fragile quantum entanglement can survive even in tough, real-world conditions.
Taken together, the result points to progress beyond controlled laboratory setups and toward practical quantum networking, where entangled particles would need to function across ordinary infrastructure and environments.
