Quantum Computing Threatens Financial Cryptography Migration

Professor Scott Aaronson said in 2026 that quantum computers will likely be capable of breaking modern public-key cryptography within five to ten years, even if broader commercial quantum advantages remain distant. He warns the cryptographic migration across banks, payment networks and FinTechs could itself consume that window, so financial institutions must begin transitioning to quantum-resistant encryption now to avoid catastrophic exposure.
