Use of discrete modulation and a continuous wave local oscillator in a 24 km continuous variable quantum key distribution system
Xuan Quyen Dinh, Zheshen Zhang, Paul L. Voss · Optical Fiber Communication Conference · 2010
We implement an experimental continuous variable quantum key distribution system over 24 km of optical fiber that uses discrete signaling and a continuous wave local oscillator. A secure key rate of 3.45 kb/s was achieved.
