THE QUANTUM INTERNET IS COMING Remember when I said China leads the quantum network race? The US just answered twice in the same week. Result one: Stony Brook and Brookhaven National Lab sent quantum information through open air across 13 miles. No cable at all. The first US demonstration of its kind. Result two: a NIST led team transmitted entangled photons across 62 kilometers of fiber. Not lab fiber but an existing, ordinary, already in the ground telecom cable. The toughest real world test the quantum internet has passed. Why both are hard: entanglement is the resource that makes quantum networks work, and it's absurdly fragile. Temperature, vibration, atmosphere, the noise of regular traffic in nearby fibers, all of it destroys quantum states. Getting them through 38 miles of commercial cable, or 13 miles of open sky is a massive feat. But kilometers aren't the whole story. China's famous 12,000 km quantum backbone runs on an older architecture, trusted relay nodes. Every few hundred kilometers the signal stops, gets measured, gets re-sent. What NIST demonstrated is the next architecture which is entanglement over real infrastructure, end to end, no trusted middlemen. And it rides fiber that's already underground. Every telecom on earth already owns the hard part. What Stony Brook demonstrated is the path off the ground entirely. Free space links are the stepping stone to quantum satellites, the one domain China has monopolized since Micius launched (Though its had its problems). So overall, China built more kilometers of the old design over a decade. The US just demonstrated the new design on buried cable AND in open air, in seven days. This race has just begun. $IONQ $RGTI $INFQ $QBTS
