Communication and cryptography based on quantum physics

Rajni Goel, Moses Garuba, Anteneh Girma

Quantum cryptography is an approach to securing communications by applying the phenomena of quantum physics. Unlike traditional classical cryptography, which uses mathematical techniques to restrict eavesdroppers, quantum cryptography is focused on the physics of information. Quantum cryptography provides secure communication, whose security depends only on the validity of quantum theory, i.e., it is guarantied directly by the laws of physics. This is a substantial difference from any classical cryptographic techniques. This article summarizes the current state of quantum cryptography and provides potential extensions of its feasibility as a mechanism for securing existing communication systems

Quantum cryptography is a new method of communication offering the security of the inviolability by using Law of Nature.Quantum Cryptography uses different secure communication by applying the phenomena of quantum physics. Unlike traditional classical cryptography, which uses mathematical techniques to restrict eavesdroppers, quantum cryptography is focused on the properties of physics of light for information. Quantum cryptography depends only on the validity of quantum theory, i.e., it is guarantied directly by the laws of physics. This is a different from any classical cryptographic techniques. This paper summarizes the current state of quantum cryptography and provides potential extensions of its feasibility as a mechanism for securing existing communication systems.

Quantum cryptography is an approach toward secure communication by applying the phenomena of quantum physics. As compared to the classical cryptography, quantum cryptography provides more secure communication whose security depends only on the validity of quantum theory. It is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. Quantum cryptography is one of the few commercial applications of quantum physics at the quantum level. The quantum relies on two important elements of quantum mechanics- the Heisenberg uncertainty principle and principle of photon polarization. This paper focuses on the principle of quantum cryptography and how this technology contributes in security of network.
