Confidential Deterministic Quantum Communication Using Three Quantum States
Journal Title: International Journal of Advanced Computer Science & Applications - Year 2011, Vol 2, Issue 11
Abstract
A secure quantum deterministic communication protocol is described. The protocol is based on transmission of quantum states from unbiased bases and exploits no entanglement. It is composed form two main components: a quantum quasi secure quantum communication supported by a suitable classical message preprocessing layer. Contrary to many others propositions, it does not require large quantum registers. A security level comparable to classic block ciphers is achieved by a specially designed, purely classic, message pre- and post-processing. However, unlike to the classic communication, no key agreement is required. The protocol is also designed in such a way, that noise in the quantum channel works in advantage to legitimate users improving the security level of the communication.
