Quantum Advantage Crossover: Market Unlock Simulator

Quantum computing markets don't grow smoothly — they switch on segment by segment, each one gated by its own hardware threshold. This simulator drives two roadmap curves, logical-qubit count and physical error rate, forward through time; the moment a market segment's required qubit count and error tolerance are both met, it "unlocks" and its revenue starts climbing on a Bass diffusion curve, the standard model economists use for new-technology adoption. Chemistry & materials simulation unlocks first, followed by finance & optimization, logistics search, and — last and hardest — cryptanalysis. Adjust the qubit doubling period, error-suppression rate and investment sentiment to see how roadmap assumptions reshape which markets exist and when.
