Abstract

In order to increase the maximum transmission distance and simplified implementation, we propose a continuous-variable quantum key distribution (CVQKD) protocol of entanglement in the middle, which the protocol is based on gaussian modulation of a single quadrature of the coherent states of light and the noiseless linear amplifier (NLA). This protocol uses the simplified unidimensional protocol to simplified implementation, and uses the NLA to increase the maximum transmission distance and tolerable excess noise in the presence of gaussian lossy and noisy channel. The simulation results show that the proposed unidimensional CVQKD protocol of entanglement in the middle with NLA obvious increased the maximum transmission distance.
