Finite-size analysis of eight-state continuous-variable quantum key distribution with the linear optics cloning machine Project supported by the National Natural Science Foundation of China (Grant Nos. 61379153 and 61572529). |
(color online) (a) PM scheme of the eight-state CV-QKD protocol: Alice obtained the random number k from a random number generator (RNG), and then modulated the original state sent from the source by the modulator. (b) The equivalent EB version of the protocol: Alice prepared a two-mode entangled state, one mode was measured to get the result k. The other state of the mode was sent to Bob. |
