Scientists transmitted quantum-entangled photons 62km through noisy, exposed overhead cables between NIST and University of Maryland without losing their quantum properties. The breakthrough used laser reference signals to correct environmental distortions from wind, temperature, and vibrations—conditions that would destroy quantum data without active stabilization.
