Quantum computers harnesses the strange features of quantum mechanics, such as superpositions, entanglement, etc. Post-Quantum Cryptography aims to secure cryptosystems against the enhanced power of such computers. On the other hand, Quantum Cryptography uses quantum computing to achieve never-before-possible cryptographic functionalities, such as programs that cannot be copied.
