Quantum Errors and Quantum Error Correction (QEC) Methods
Quantum error correction (QEC) is therefore critical for enabling large-scale or fault-tolerant quantum computing. Fault tolerance means a quantum computer can continue to operate correctly even when individual operations or qubits error out. Unlike classical error correction – which can…

Inside NIST’s PQC: Kyber, Dilithium, and SPHINCS+
In 2022, after a multi-year evaluation, NIST selected CRYSTALS-Kyber, CRYSTALS-Dilithium, and SPHINCS+ as the first algorithms for standardization in public-key encryption (key encapsulation) and digital signatures. Kyber is an encryption/key-establishment scheme (a Key Encapsulation Mechanism, KEM) based on lattice problems,…
