The continuous variable quantum key distribution has been considered to have practical solution to provide high key rate. This paper explains the difference between DV-QKD and CV-QKD schemes. It describes CV-QKD as a theory that satisfies the uncertainty principle using continuous variable and homodyne detector. We shows varying length of secret key in QKD systems and amount of the exposed information to amplify privacy.
