Abstract

We report the first demonstration of using the Quantum Instrumentation and Control Kit (QICK) system on RFSoC-FPGA technology to drive the electro-optic intensity modulator that generate time-bin entangled photon pairs and to detect the photon signals. With the QICK system, we achieve high levels of performance metrics including coincidence-to-accidental ratio exceeding 150, and entanglement visibility exceeding 95%, consistent with performance metrics achieved using conventional waveform generators. We also demonstrate simultaneous detector readout using the digitization functional of QICK, achieving internal system synchronization time resolution of 3.2 ps. The work reported in this paper represents an explicit demonstration of the feasibility for replacing commercial waveform generators and time taggers with RFSoC-FPGA technology in the operation of a quantum network, representing a cost reduction of more than an order of magnitude.

使用量子仪器控制套件系统的纠缠光子对源演示器

我们报告了首次使用量子仪器和控制套件(QICK)系统在RFSoC-FPGA技术上驱动产生时间bin纠缠光子对的电光强度调制器并检测光子信号的演示。使用QICK系统，我们实现了高水平的性能指标，包括超过150的巧合比，超过95%的纠缠可见性，与使用传统波形发生器实现的性能指标一致。我们还演示了使用QICK数字化功能的同步检测器读出，实现了3.2 ps的内部系统同步时间分辨率。本文报告的工作明确展示了在量子网络运行中用RFSoC-FPGA技术取代商用波形发生器和时间标记器的可行性，代表了成本降低超过一个数量级。

期刊介绍： The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
