Continuous-variable quantum key distribution based on photon addition operation
《Chinese Physics B》2021年第6期126-132,共7页Xiao-Ting Chen Lu-Ping Zhang Shou-Kang Chang Huan Zhang Li-Yun Hu 
supported by the National Natural Science Foundation of China (Grant Nos. 11664017 and 11964013);the Training Program for Academic and Technical Leaders of Major Disciplines in Jiangxi Province,China (Grant No. 20204BCJL22053)。
It is shown that the non-Gaussian operations can not only be used to prepare the nonclassical states, but also to improve the entanglement degree between Gaussian states. Thus these operations are naturally considered...
