Abstract :
Summary form only given. We propose a new approach, based on a single side band (SSB) detection scheme, that allows the BB84 protocol to be used in a robust scheme for quantum cryptography and eliminates both polarization and path-delay maintenance problems. An unbalanced integrated Mach Zehnder modulator modulates the intensity of the reference beam.
