Classical computers use bits, whilst quantum computers use quantum bits (qubits).Quantum computers can perform tasks that classical computers are unable to perform.When ideal quantum computers are developed, they will be a serious threat to current encryption systems.This has prompted the development of post-quantum cryptography.The National Institute of Standards and Technology (NIST) have selected four post-quantum algorithms.Three employ lattice-based cryptography, whilst one employs hash-based cryptography.Although recent attacks on lattice-based cryptography mean that the post-quantum algorithms of the future are uncertain.
