Advantages of Classical Cryptography Over the Quantum Cryptography

Quantum cryptography is having lots of consideration in present time for security but its important to note that implementation of algorithms using QC is not viable if one wants to have the security intact. A technique needs to be theoretically strong and also practically viable. But quantum cryptography comes to naught in the latter. It can only be used to share keys using Quantum Key Distribution (QKD). Distribution of keys is just a part of securing information. In this paper first we explain the classical cryptography (CC) and the concept of quantum cryptography (QC) then we explain the various advantages of CC over QC.
