It was not in the quiet of a lecture hall, but in the steady rhythm of a cleanroom, that quantum computing learned to endure—not as a fleeting marvel, but as something meant to be made again, and again, and again.
It happened once before—on a quiet afternoon in 1959 at Fairchild Semiconductor—when Jean Hoerni sketched the planar process, a way to build transistors on silicon wafers that could be mass-produced. No one realized it then, but that single idea would seed the entire microelectronics revolution. Today, we’re witnessing its quantum echo: not with doped silicon junctions, but with spin states in quantum dots, now being etched onto 300 mm wafers inside the same kind of cleanrooms that once birthed the first integrated circuits. The real breakthrough isn’t just the 4 ms coherence time—it’s that this was achieved not in a university basement lab, but in an industrial foundry where reproducibility trumps elegance. Like the planar process before it, this moment signals the transition from quantum science to quantum engineering, where the true innovation lies not in isolation, but in integration. The future of quantum computing may not come from a flash of genius in a lab, but from the slow, relentless refinement of processes on a factory floor—where the most powerful technologies are no longer discovered, but manufactured.
