#quantumcomputing #chinasemiconductor #chipwar China just published a quantum computing result that should be making strategic planners in Washington very uncomfortable. On May 13, 2026, the journal Nature published a peer-reviewed paper from the University of Science and Technology of China revealing Jiuzhang 4.0 — a photonic quantum machine that performed a specialized sampling task in 25 microseconds. The world's fastest classical supercomputer would need 10 to the 42nd power years to do the same thing. But the real story is not the speed. It is the architecture. Because Jiuzhang 4.0 does not use a single piece of technology on America's export control list. No EUV lithography. No TSMC fabrication. No NVIDIA GPUs. No advanced silicon at all. It runs on light — photons, mirrors, beam splitters, and optical detectors. The chip war was designed to contain silicon. China just demonstrated that the next computing frontier may not need silicon at all. In this video, we break down: — What
