The field of study known as “quantum cryptography” focuses on utilizing the peculiar characteristics of quantum mechanics in order to carry out various cryptographic operations. In contrast to more conventional cryptographic systems, quantum cryptography uses physics rather than mathematics as a primary component of its security model.
This is one of the primary ways in which quantum cryptography differentiates itself from traditional cryptographic approaches. The advantage of quantum cryptography lies in the fact that it enables the completion of a variety of cryptographic tasks that have been demonstrated or conjectured to be impossible using only classical (i.e., non-quantum) communication.
This is the case because quantum cryptography allows for the transmission of information in a manner that is indistinguishable from that of classical communication. Moreover, quantum cryptography also has the advantage of being able to guarantee the security of any transmitted information, as quantum mechanics provides a means of detecting eavesdropping.
