摘要

本文提出了一种基于放大自发发射（ASE）噪声的64 gb /s量子随机数发生器（QRNG）方案。利用市售的200 mhz带宽光电探测器，实验证明了1.05 gb /s的单通道吞吐量。同时，我们开发了一种新的双速率循环移位异或（DRCS-XOR）算法，以减轻符号间的相关性，提高功率谱密度的均匀性。提出的DRCS-XOR算法以实时效率为优先级，复杂度为0 (n)，而其安全性依赖于ASE的量子熵优势。通过将宽带ASE熵提取与具有成本效益的光电元件协同集成，所提出的架构实现了高生成速率，克服了传统量子随机数生成系统固有的带宽效率权衡限制。

Low-cost commercial optoelectronic components-driven quantum random number generator with theoretical 64 Gb/s throughput via parallelization

In this work, a feasible 64-Gb/s quantum random number generator (QRNG) scheme based on amplified spontaneous emission (ASE) noise is proposed. A single-channel throughput of 1.05-Gb/s was experimentally demonstrated using commercially available 200-MHz-bandwidth photodetectors. Meanwhile, we develop a novel dual-rate cyclic shift XOR (DRCS-XOR) algorithm to mitigate inter-symbol correlations and enhance the uniformity of the power spectral density. The proposed DRCS-XOR prioritizes real-time efficiency with the complexity of O(n), while its security depends on the quantum entropy dominance of ASE. By synergistically integrating broadband ASE entropy extraction with cost-effective optoelectronic components, the proposed architecture achieves high generation rate and overcomes limitations in bandwidth-efficiency tradeoffs inherent in conventional quantum random number generation systems.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
