量子密钥分发（QKD）基于量子物理定律提供信息论安全的密钥建立方式，但其实际应用范围受限于光子硬件的高昂成本及现有仿真工具的碎片化特性。大多数仿真器仅支持单一协议，且仅报告单次随机运行的结果，这使得系统的协议比较和可复现的统计推断难以实现。本文提出了一个统一的QKD仿真平台，该平台在单一Python/Qiskit引擎中实现了BB84、B92、E91和BBM92这四种基础协议。共享的损伤模型涵盖光纤衰减、光源与探测器损耗、偏振漂移以及可配置的截获-重发窃听。该平台通过两个共享同一后端的独立接口实现访问：用于本地实验的桌面应用（Tkinter、Matplotlib）和用于零安装远程访问的基于浏览器的Web客户端（React，链接为this http URL）。所有报告的结果均来自重复运行研究（20次独立运行，每次使用10000个量子比特），全程给出均值、标准差和95%置信区间。在25公里光纤链路下，BB84实现了最高的平均密钥率，为160045 Hz，其次是BBM92（80023 Hz）、E91（52815 Hz）和B92（40011 Hz），该排序与仿真得到的筛选效率精确匹配。在E91协议下，CHSH S统计量在基线状态下的平均值为2.12，当激活窃听者时降至1.58，证明了基于贝尔不等式的入侵检测与量子比特错误率（QBER）无关
英文摘要
Quantum Key Distribution (QKD) offers information- theoretically secure key establishment grounded in the laws of quantum physics, yet its practical reach is limited by the prohibitive cost of photonic hardware and the fragmented nature of existing simulation tools. Most simulators support only a single protocol and report results from individual stochastic runs, making systematic protocol comparison and reproducible statistical inference difficult. This paper presents a unified QKD simulation platform that implements four foundational protocols BB84, B92, E91, and BBM92 within a single Python/Qiskit engine. A shared impairment model covers fiber attenuation, source and detector losses, po- larization drift, and configurable intercept-resend eavesdropping. The platform is accessible through two independent interfaces that share the same backend: a desktop application (Tkinter, Matplotlib) for local experimentation and a browser-based web client (React, Node.js/Express) for zero-install remote access. All reported results are drawn from repeated-run studies (20 independent runs, 10000 qubits each), with mean, standard deviation, and 95% confidence intervals stated throughout. At a 25 km fiber link, BB84 achieves the highest mean key-rate of 160,045 Hz, followed by BBM92 (80023 Hz), E91 (52815 Hz), and B92 (40011 Hz) ordering that tracks simulation-derived sifting efficiencies precisely. Under the E91 protocol, the CHSH S-statistic averages 2.12 at baseline and falls to 1.58 when an eavesdropper is activated, demonstrating Bell-inequality-based intrusion detection independent of QBER
