Quantum simulations with ultracold atoms typically create atomic wave functions with structures at
optical length scales, where direct imaging suffers from the diffraction limit. In analogy to advances in
optical microscopy for biological applications, we use a nonlinear atomic response to surpass the
diffraction limit. Exploiting quantum interference, we demonstrate imaging with superresolution of ?=50
and excellent temporal resolution of 500 ns. We characterize our microscope’s performance by measuring
the ensemble-averaged probability density of atoms within the unit cells of an optical lattice and observe
the dynamics of atoms excited into motion. This approach can be readily applied to image any atomic or
molecular system, as long as it hosts a three-level system.
