论文摘要
扩增的自发发射（ASE）噪声已被广泛研究并用于构建量子随机数发生器（QRNG）。虽然先前的相对作用主要集中在QRNG系统的实现和验证上，但对ASE噪声的一般检测的综合物理模型和随机性定量仍然不完整，这对于定量安全性分析至关重要。在本文中，开发和验证了用于发射，检测和采集ASE噪声的系统物理模型，基于在各种设置下进行数值模拟，并且模拟结果与相应的实验数据非常吻合。然后，提出和验证了一种随机定量方法和相应的实验可验证方法，该方法量化了量子过程所产生的随机性，并根据ASE噪声的检测来改善QRNG的安全性分析。本文提出的物理模型和随机定量方法具有显着的可行性，适用于QRNG系统，随机性源自具有任意分布的光子数的检测。
The amplified spontaneous emission (ASE) noise has been extensively studied and employed to build quantum random number generators (QRNGs). While the previous relative works mainly focus on the realization and verification of the QRNG system, the comprehensive physical model and randomness quantification for the general detection of the ASE noise are still incomplete, which is essential for the quantitative security analysis. In this paper, a systematical physical model for the emission, detection and acquisition of the ASE noise with added electronic noise is developed and verified, based on which the numerical simulations are performed under various setups and the simulation results all significantly fit well with the corresponding experimental data. Then, a randomness quantification method and the corresponding experimentally verifiable approach are proposed and validated, which quantifies the randomness purely resulted from the quantum process and improves the security analysis for the QRNG based on the detection of the ASE noise. The physical model and the randomness quantification method proposed in this paper are of significant feasibility and applicable for the QRNG system with randomness originating from the detection of the photon number with arbitrary distributions.
