Extended Data Fig. 5: Imaging survival details.
From: A tweezer array with 6,100 highly coherent atomic qubits
a, Map and histogram of the imaging survival probability per site across the tweezer array, as characterized using the three-image analysis of data from 16,000 iterations. Note that the vertical axis of the histogram is plotted on a log scale. The mean of the site-resolved imaging survival probability is 99.985% and the minimum value is 99.66%. b, Predicted upper bound on the probability of detecting a defect-free array after an ideal rearrangement sequence (estimated as p(1|1)n, in which n is the number of atoms in the first image), limited by imaging survival and false positives. The threshold in the first image can be displaced to reduce false positives, at the cost of excluding some atoms. Note that we may ignore the issue of false negatives in the first image, as we can always physically eject residual atoms in sites that are determined to be negative.
