Paper Abstract

Quantum cryptography is a new, multidisciplinary technique of distributing information to two or more parties in such a way that can guarantee security against an unauthorized eavesdropping attempt. In the presented paper three schemes of implementation of this goal by means of fiber optics, namely a scheme based on photon polarization, delayed interferometry, and quantum correlations of nonorthogonal states, are discussed. Realization of the proposed schemes is discussed as well as fundamental limits imposed on quantum cryptography by fiber-optics technique.
