  • Abstract
    We propose a modified no-switching continuous-variable quantum key distribution protocol to improve the secret key rate and maximum transmission distance by inserting a noiseless linear amplifier at the output of quantum channel. Security analysis shows that a noiseless linear amplifier with gain g can increase the maximum transmission distance of no-switching protocol by 100log10g km
