quantum key distribution

Researchers led by Leibniz Hannover, Stuttgart, and Nanjing have published the first time-bin QKD link driven by an on-demand telecom quantum dot, holding stable across 120 km of standard fiber for six hours straight.

India's National Quantum Mission has demonstrated a 1,000-kilometer quantum-secured communication network using QNu Labs' indigenous ARMOS QKD platform, reaching the halfway mark of its 2,000 km target in under two years — well ahead of the original eight-year timeline.

Quantum Computing Inc. installed its Dirac-3 quantum optimization machine on the Quantum Corridor network connecting Chicago and Hammond, Indiana, marking the first time a quantum computer has been deployed on a QKD-secured commercial fiber network spanning U.S. state lines.
