Prefer Open US Quantum Development

Experts and recent papers suggest fault‑tolerant quantum computers capable of breaking common public‑key cryptography could arrive within a decade. Given that companies racing to build them have no intention of pausing, policymakers face a choice: encourage open, primarily US‑based development and accelerate defensive migration (post‑quantum crypto), or risk stealth builds by adversaries that tighten attack windows. — This reframes the 'quantum threat' from a purely technical forecasting problem into an active industrial‑security policy decision with immediate implications for encryption standards, procurement, and international tech competition.
