Abstract :
In this work we present the principles and experimental demonstration of a BB84 quantum key distribution (QKD) one way system using fainted pulses and a quadrature phase-shift-keying (QPSK) format including a time- multiplexed unmodulated carrier reference at Alice´s end, and a differential homodyne reception at Bob´s end. We also describe the secure electronics interface subsystem concept for the interaction with upper layers in an IP application.
