Short URL:  https://www.nist.gov/pqcrypto For a plain-language introduction to post-quantum cryptography, see What Is Post-Quantum Cryptography?   PQC Standards  |  Migration to PQC  |  Ongoing PQC Standardization Process NIST’s Post-Quantum Cryptography (PQC) project leads the national and global effort to secure electronic information against the future threat of quantum computers—machines that may be years or decades away but could eventually break many of today’s widely used cryptographic systems. Through a multi-year international competition involving industry, academia, and governments, NIST released the principal three PQC standards in 2024 and is developing additional standards to serve as backups or alternatives. Organizations should begin applying these standards now to migrate their systems to quantum-resistant cryptography. Alongside these standards, NIST conducts foundational cryptographic research; collaborates with industry and federal partners to guide organizations preparing for PQC...
