THE DESIGN AND CONSTRUCTION OF A QUANTUM MATTER SYNTHESIZER
Quantum 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.
In this talk, I describe progress toward the completion of 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.
Several technical aspects will be highlighted, including the digital-micromirror device tweezer array and dual-objective setup. Initial results on the site-resolved atom imaging and a high-efficiency loading scheme are presented. I also report on our development of a novel superresolution imaging technique for cold atoms in an optical lattice, where we demonstrated a full-width-at-half-maximum resolution of 32(4) nm.
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.
