Multi-Stage CD-Kennedy Receiver for QPSK Modulated CV-QKD in Turbulent Channels
Renzhi Yuan, Zhixing Wang, Shouye Miao +4
Continuous variable-quantum key distribution (CV-QKD) protocols attract increasing attentions in recent years because they enjoy high secret key rate (SKR) and good compatibility w…
