Quantum computing spent six years living down a single word. When Google declared "quantum supremacy" in 2019 on its Sycamore chip, the result ran a task with no application, and classical algorithms later narrowed the claimed gap. The period from April 2025 to April 2026 is defined by the field's attempt to replace…
