Extended Data Fig. 4: Validation of two and three particle quantum walks in one dimension.
From: An atomic boson sampler

The full output distribution after binning for a, two and b, three particles initialized at nearest-neighbor spacing, at an evolution time of tHOM and 2tHOM respectively. The grey bars are theory for error-free state preparation, evolution, and detection with parity projection, and the black points are data. The upper row corresponds to distinguishable (Dist.) atoms, and the bottom row to unlabelled, nominally indistinguishable (Indist.), atoms. The outputs are grouped by the number of collisions (1, 2, or 3 atoms on the same site) that occur after binning, indicated by the inset cartoons.
