Rate-Adaptive Protocol for Continuous Variable Key Reconciliation
摘要
Abstract
Quantum key distribution (QKD) enables two legal parities to share a secure key.Information reconciliation is an essential process in quantum key distribution.Low-density parity-check (LDPC) codes,which belong to the class of linear error correcting codes and perform at rates extremely close to the Shannon capacity,can achieve the key reconciliation with high efficiency.Considering a time-varying channel in practical continuous variable QKD system,we propose a rate-adaptive protocol for continuous variable key reconciliation,which can cover a broad range of signal-to-noise ratio and achieve higher reconciliation efficiency.关键词
