Probing critical phenomena in open quantum systems using atom arrays

This dataset contains the experimental and numerical data supporting the publication “Probing critical phenomena in open quantum systems using atom arrays”. The data were obtained using a programmable Rydberg quantum simulator based on a two-dimensional cesium atom array. The experiments explore quantum critical behavior in both one-dimensional and two-dimensional geometries, focusing on the Ising universality class. By adiabatically preparing critical ground states and systematically tuning the openness of the system, we directly measured real-space correlations and extracted the corresponding scaling dimensions. The repository includes processed data files for the key figures in the main text and supplementary materials, together with descriptions that allow reproduction of the plots and numerical comparisons presented in the paper. Raw atom logicals datasets are available from the authors upon reasonable request.
