Mathematical description of polarization distortion of signal in quantum cryptography systems
Abstract
We discuss an analytical model that describes polarization distortion of an optical signal that appears during its propagation in a fiber optics line. The model is applied for illustrating the principles of weak signal distortion compensation in different types of quantum cryptography systems.
