Experiments on a Quantum Matter Synthesizer

The "Quantum Matter Synthesizer" is a new experimental apparatus capable of single-site atom imaging and re-arrangement through the use of dual high numerical aperture microscopes and moveable tweezer arrays. Cold cesium atoms are first stochastically loaded into an 2D triangular lattice Subsequently, degenerate Raman sideband cooling is applied to the atoms and their fluorescence is collected on a low-noise CCD to image the atomic distribution in the lattice. A re-arrangement algorithm computes tweezer trajectories to bring the atoms to a desired configuration. The computed moves are then streamed to a digital micromirror device, which is capable of moving an array of tweezers at the switching speed of 2 kHz. After re-arrangement, the atoms are again cooled and their final distribution imaged. We will report our progress toward the completion of the system.
