    Abstract

    Continuous variable quantum key distribution relies on the transmission of weakly modulated coherent states and the detection of optical field for secure communication. In this talk, we give an overview of recent developments in continuous variable quantum key distribution. In particular, we discuss a scheme that uses continuous-wave laser beams without optical pulsing. Due to its continuous wave nature, our scheme is intrinsically broadband and does not require measurement basis switching. Finally, we present a status report on integration of this system into existing communication infrastructures at the Parliamentary Triangle of Australia in Canberra.
