This interactive timeline spans the full history of quantum computing from Feynman's 1981 proposal to the present day. Events are color-coded by category: theory (blue), hardware (green), industry (orange), and milestone (red). Use the filter buttons to focus on a single category, scroll and zoom to explore different eras, and click any event to see what was claimed at the time versus what actually happened.
