Extended Data Figure 6: Full time evolution of the experimental correlation function for the 7 × 7 square array.
From: Tunable two-dimensional arrays of single Rydberg atoms for realizing quantum Ising models

One observes the blockaded region around (k, l) = (0, 0), with a slight flattening reflecting the anisotropy of the interaction. After a few Ω−1, the correlation function g(2)(k, l) does not evolve any more.
