摘要

单光子的衰减特性及其易受干扰的缺点限制了纯单光子量子系统的传输码率及距离.弱相干光脉冲(WCP)光源和准单光子源(HSPS)则具有更高的实用价值.本文将这两种光源和诱发态方案相结合并采用Lütkenhaus和Gottesman-Lo- Lütkenhaus-Preskill (GLLP)两种数据后处理方法进行性能分析.仿真结果表明:HSPS在传输距离上要优于WCP,对应相同传输距离时系统量子误码率(QBER)要小些,但相对密钥生成率低.

Abstract

Since the single photon is easy to attenuate and be disturbed, its key generation rate and transmission distance in quantum communication systems are generally limited. In contrast, weak coherent pulse (WCP) and heralded single photon source (HSPS) exhibit higher feasibility than the single photon source in quantum key distributions (QKD). We compare the performances of QKD using these two kinds of photon sources and decoy state method, incorporating data-postprocessing methods including the Lütkenhaus scheme and Gottesman-Lo-Lütkenhaus- Preskill (GLLP) scheme. Simulation results indicate that QKD using HSPS can transmit longer distance than using WCP with lower overall quantum bit error rate (QBER) at the same transmission distance, albeit with relatively low key generation rate.
