Abstract

This paper demonstrates a boson sampler using ultracold atoms in a two-dimensional, tunnel-coupled optical lattice. The system features fast and programmable preparation of large atom ensembles, propagation with low loss, and high-fidelity detection. Experiments involving up to 180 atoms are presented, focusing on targeted tests to verify indistinguishability, characterize unitary evolution, and observe bunching features. Direct verification of boson sampling distributions is infeasible at this scale, necessitating these alternative tests.
