We present a model for the quantum-bit error rate
in a polarization-encoding system for transmission of quantum
information, without compensation of polarization. The random
evolution of the polarization along the fiber is induced by its
polarization mode dispersion. An experimental setup able to
measure the quantum-bit error rate in the transmission of the
photons through several fiber lengths is proposed, and some
experimental results are obtained. Our experimental scheme is
designed to work on the 1550 nm telecom band.
