摘要：Quantum cryptography uses the law of quantum physics for unconditionally secure data communications. This is a main achievement because the cryptography currently in use, known as conventional cryptography, relies completely on the hardness of a mathematical equation. The advances in quantum computing has threatened the computational security of classical cryptography, which in theory can efficiently compute the hard mathematical problems classical cryptography relies on. This paper makes a comparison between classical cryptography and quantum cryptography and outlines the increased security level provided by quantum cryptography
