Summary, Etc.  

요약Quantum simulation using ultracold atoms is a rapidly-advancing field that has made significant contributions toward our understanding of quantum many-body phenomena. The frontier of quantum simulation is tied to our ability to prepare and measure the quantum state with high fidelity.This thesis describes the quantum matter synthesizer (QMS), a new experimental platform in which individual particles in a lattice can be resolved and re-arranged into arbitrary patterns. The ability to spatially manipulate ultracold atoms and control their tunneling and interactions at the single-particle level allows full control of a many-body quantum system.The envisioned experimental sequence is as follows. 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 in small discrete steps at a speed of 2.5 kHz. After re-arrangement, the atoms are again cooled and their final distribution imaged, at which point the quantum matter is ready for quantum simulation.We present the design and characterization of the QMS, and highlight several initial results, which include a new super-resolution imaging method for cold atoms, site-resolved imaging of the atoms, and an efficient loading scheme capable of producing lattices with 74% filling. Once completed, the QMS will enable detailed studies in quantum transport and quantum phase transitions where the initial state is deterministically prepared and the final state is measured with single-site resolution.
