The present research of international quantum cryptography communication is summarized and analyzed, several quantum cryptography communication systems are introduced and compared, and a new system based on polarization code' is given.
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. The security of these transmissions is based on the inviolability of the laws of quantum mechanics. The quantum cryptography relies on two important elements of quantum mechanics-the Heisenberg Uncertainty principle and the principle of photon polarization. This paper summarizes the current state of quantum cryptography and the real–world application implementation of this technology.
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 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.
