Abstract: In this paper, we investigate the effect of chromatic dispersion on a continuous variable quantum key distribution system with heterodyne detection, in which information is encoded in the sidebands of modulated laser radiation. We consider the system in which a balanced detector output is downconverted to an intermediate frequency and propose a non-standard methods of dispersion compensation using RF phase shifters.
Keywords: heterodyne detection, subcarrier wave, quantum key distribution, chromatic dispersion.
