Photon subtraction-based continuous-variable measurement-device-independent quantum key distribution with discrete modulation over a fiber-to-water channel
文献摘要：
We propose a discrete-modulated continuous-variable measurement-device-independent quantum key distribution protocol over a fiber-to-water channel.Different from optical fibers,the underwater channel has more severe optical attenuation because of optical absorption and scattering,which reduces the maximum communication distance.To enhance the performance of the protocol,the photon subtraction operation is implemented at the modulator side.We carry out a performance simulation in two different kinds of seawater channel,and the result shows that the scheme with photon subtraction has a longer secure communication distance under certain conditions.
