Abstract :
Summary form only given. We report an experimental demonstration of a BB84 QKD one-way system using fainted pulses and a QPSK key format including a time-multiplexed unmodulated carrier reference at Alice´s end, and a differential reception at Bob´s end (Hirano, et.al., 2003), in which phase drift and polarization mismatch are two critical impairments to overcome.
