Abstract: Disclosed is a time division quadrature homodyne CV QKD system, and a continuous variable quantum key distribution system which includes: a transmitter generating an optical pulse of quantum state data by using continuous light according to data of a transmission target encryption key; and a receiver separating the optical pulse received from a channel into two paths and fixing phases of two signals having a time difference of one period of the optical pulse to orthogonal phases, and then generating bit information through state detection by a time division homodyne detection from interacted signals.
