Wigner Time通过数据化表示实验时间线，解决了传统实时系统耦合紧密、难以复用的问题，已在冷原子实验中提升五倍时间分辨率。
AI中文摘要：
在原子、分子和光学物理中，精确计时的多设备控制由专门的实时系统提供，这些系统对实验的描述施加了自身的术语：一个基于全局时钟的程序，其中每个阶段的边界是根据其之前所有内容计算的绝对时间。此类描述紧密耦合——更改一个阶段会影响所有后续阶段——并且相应地难以重用、检查或迁移到其他地方。我们引入了Wigner Time，一个Python包，其中实验过程被表示为数据：一个定时更新的表格，通过组合函数组装，并引用实验中的命名点而非绝对时刻。硬件仅在最终的转换步骤中进入，使描述保持可读且与后端无关。Wigner Time已运行两个冷原子装置超过两年，用其替换手写实时程序将可实现的时间分辨率提高了五倍；该设计适用于任何需要精确多设备计时的领域。
英文摘要：
Precisely timed, multi-device control in atomic, molecular and optical physics is provided by specialized real-time systems, which impose their own terms on the description of the experiment: a program over a global clock, in which every stage boundary is an absolute time computed from everything preceding it. Such descriptions are tightly coupled -- changing one stage affects all later ones -- and are correspondingly hard to reuse, inspect, or move elsewhere. We introduce Wigner Time, a Python package in which the experimental procedure is instead represented as data: a table of timed updates, assembled by composing functions and referred to named points in the experiment rather than to absolute instants. Hardware enters only at a final conversion step, leaving the description readable and back-end agnostic. Wigner Time has run two cold-atom setups for more than two years, where replacing a hand-written real-time program improved the achievable temporal resolution five-fold; the design applies to any domain requiring precise multi-device timing.
