Wigner Time introduces a data-oriented framework for managing precise multi-device timing in quantum experiments, decoupling experimental logic from absolute clock dependencies to improve reusability and temporal resolution. By representing procedures as composable functions rather than rigid programs, this tool addresses critical software challenges in atomic, molecular, and optical physics without relying on AI or machine learning techniques.
Wigner Time: a data-oriented approach to experimental timeline creation for quantum science and technology
arXiv:2609.06230v1 Announce Type: new Abstract: 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.
