摘要

摘要量子通信的应用需求越来越大,包括真随机数和量子密钥分发。放大自发辐射(ASE)是一种量子物理过程,在这两种情况下都可以发挥重要作用。建立了一种用于检测和获取ASE噪声的物理模型。计算了光子的概率,并给出了光子与系统参数的关系。实验结果定量验证了物理模型;仿真结果与实验数据吻合较好。

Modeling of Amplified Spontaneous Emission Noise for Quantum Communication Applications
Abstract There is an increasing need for quantum communication applications, including true random numbers and quantum key distribution. The Amplified Spontaneous Emission (ASE) is a quantum physics process, which can play a significant role in both cases. A physical model for detecting and acquiring the ASE noise is developed. The photon probability is calculated, and the relationship with system parameters is presented. Experimental results quantitatively validate the physical model; the simulation results all significantly fit the corresponding experimental data well.
