Quantum Matter Synthesizer: Seeing and Controlling Individual Atoms

We present progress on the construction of a "quantum matter synthesizer," a new experimental apparatus that integrates site-resolved imaging of atoms in a sub-micron lattice with dynamic control using a moveable tweezer array. Cold cesium atoms are first stochastically loaded into a static 2D triangular optical lattice. Subsequently, degenerate Raman sideband cooling is applied to the atoms and the resulting fluorescence is collected on a low-noise CCD to image the site occupancies. A re-arrangement algorithm computes tweezer trajectories to bring atoms to a desired configuration. The computed moves are streamed to a digital micromirror device (DMD), which projects the tweezer array with a fast switching speed of 2 kHz. After re-arrangement, the atoms are again cooled and their final distribution imaged. We characterize the single-site imaging fidelity and the DMD tweezer generation.
