SIMULATION STUDY ON REVERSE RECONCILIATION OF A CONTINUOUS VARIABLE QUANTUM KEY DISTRIBUTION SYSTEM

摘要：

We have demonstrated a reverse reconciliation of a continuous-variable quantum key distribution system with efficient low-density parity check codes. A standard coded modulation technique, called MultiLevel Coding/MultiStage Decoding scheme, is used to optimize the reconciliation. Via a numerical simulation, we get the results that efficiency of the reconciliation algorithm reaches 0.89 while the final secure key distribution rate of the whole system is more than 2.2 kbits/s over 20 km of single-mode optical fiber.
