Stony Brook University launched the Quantum Frontiers initiative on April 17, 2026, unveiling the longest functional quantum network in the United States, 140 kilometers of fiber across New York purpose-built for physically unhackable data transmission. The network is intended as a testbed for quantum key distribution at metropolitan scale.
Key Points
140 km of fiber across New York State
Purpose-built for quantum key distribution
Largest functional quantum network in the U.S.
Why It Matters
The U.S. now has a production-scale testbed for quantum-secure networking, a hedge against the accelerating quantum-decryption threat.
