Articles whose subject is post-quantum cryptography: the algorithms designed to resist an adversary with a large quantum computer, and the hardness assumptions they rest on. This covers the NIST standards (ML-KEM for key encapsulation, ML-DSA and SLH-DSA for signatures), the lattice problems behind them such as SIS and Module-LWE, and hash-based one-time signatures like Winternitz.
The category also holds implementation walkthroughs of these standards and analyses of how a whole protocol stands against Shor's and Grover's algorithms. An article that only has a section on quantum resistance, within a broader subject, stays in its own category.

The NIST post-quantum standards ML-KEM, ML-DSA, SLH-DSA and FN-DSA, what each replaces, and where Cloudflare, Google, Apple, AWS and Signal run them in 2026.

Which parts of the Zama protocol resist a quantum adversary and which do not: TFHE and the threshold MPC stand on lattices and information theory, ML-KEM already ships in production, and the gap is one pairing-based proof plus the host chain's signatures.
