中文摘要 AI 辅助

我们提出了量子原子控制套件（QuACK），这是一种基于FPGA的低成本控制系统，为操作中性原子光镊阵列实验提供内存高效、精确的信号定时和低延迟的基于测量的决策。该系统由一个通过USB 3.0连接到主机计算机的FPGA模块和多个通过电缆连接的模块化子板组成，支持多种可配置的I/O格式。在本工作中，演示了数字输入、数字输出以及模拟输出。多个实验序列段可以以5 ns的时间分辨率进行编码。片上条件内核能够基于数字输入在段之间快速分支，消除了时间关键决策中的主机干预，而高速USB通信允许快速序列更新和主机级编排。我们演示了在光镊中初始装载和重新排列中性镱-171原子。高分辨率定时、片上逻辑和分布式编排架构的结合，使得该系统非常适合追求量子信息科学应用的原子、分子和光学（AMO）实验。

英文摘要

We present the Quantum Atom Control Kit (QuACK), a low-cost FPGA-based control system that provides memory-efficient precise signal timing and low-delay measurement-based decision making for operating neutral atom optical tweezer array experiments. The system consists of an FPGA module connected to a host computer via USB 3.0 and multiple cable-connected modular daughterboards enabling a myriad of configurable I/O formats. In this work, digital input and output as well as analog outputs are demonstrated. Multiple experimental sequence segments can be encoded with 5 ns timing resolution. On-chip condition kernels enable fast branching between segments based on digital inputs, eliminating host intervention for time-critical decisions, while high-speed USB communication allows rapid sequence updates and host-level orchestration. We demonstrate initial system loading and rearranging neutral ytterbium-171 atoms in optical tweezers. The combination of high-resolution timing, on-chip logic, and distributed orchestration architecture makes this system well suited for atomic, molecular, and optical (AMO) experiments pursuing applications in quantum information science.
