Abstract

White Gaussian noise (WGN) is widely used in communication system testing, physical modeling, Monte Carlo simulations, and electronic countermeasures. WGN generation relies heavily on random numbers. In this work, we present an implementation of WGN generation utilizing a quantum entropy source chip for the first time. A photonic integrated chip based on the vacuum state scheme generates quantum random numbers at a real-time output rate of up to 6.4 Gbps. A hardware-based inversion method converts uniform quantum random numbers into Gaussian random numbers using the inverse cumulative distribution function. Subsequently, the WGN signal is generated through a digital-to-analog converter and amplifiers. The WGN generator is characterized by a bandwidth of 230 MHz, a crest factor as high as 6.2, and an adjustable peak-to-peak range of 2.5 V. This work introduces a novel approach to WGN generation with information-theory provable quantum random numbers to enhance system security.

期刊介绍： Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
