Quantum Computing Is a Present-Tense Governance Issue: A General Counsel’s Roadmap for Privacy, Security and Compliance
No publicly known quantum computer can presently defeat the public-key cryptography on which modern commerce depends. The timing of a “cryptographically relevant” quantum computer remains contested. Yet adversaries do not need to wait. They can collect encrypted information today and attempt to decrypt it later—a strategy commonly called “harvest now, decrypt later.” At the same time, large organizations may need years to locate cryptography embedded across applications, cloud services, connected products, operational technology, certificates, digital signatures, and third-party platforms.
