Original Abstract Submitted
a method sequentially transmits signals of polarization states of light through an optical fiber. the optical fiber being a polarization preserving optical fiber. for each signal, a signal state is prepared as one out of a set of at least two non-orthogonal polarization states of light and sent through the optical fiber from a sender site to a receiver site. a method for quantum key distribution using polarization states of light is performed, wherein an alphabet of elementary information values is encoded in a set of non-orthogonal polarization states of light such that each elementary information value is represented by at least one of the polarization states. a classical message of elementary information values out of the alphabet is prepared, wherein the respective polarization states corresponding to the elementary information values of the classical message are prepared at a sender site as signal states.
