Construction of a Quantum Matter Synthesizer

ORAL

Abstract

We report progress on the construction of a new platform to manipulate ultracold atoms. The “Quantum Matter Synthesizer (QMS)” will have the capability of deterministically preparing large 2D arrays of atoms with single site addressability. Cesium atoms are first transferred into a science cell (specially textured to reduce reflectance to ~0.1\% across a wide range of wavelengths and incident angles) via a moving 1D lattice, where they are loaded into a magic-wavelength, far-detuned 2D optical lattice. Two NA=0.8 microscope objectives surround the science cell from above and below. The higher objective will be used to project an array of optical tweezers created via a digital micromirror device (DMD) onto the atoms, while the lower objective will capture the site-resolved fluorescence image of the atoms in the lattices and tweezers. We provide updates on our magnetic-optical trap and Raman-sideband cooling performance, characterization of the resolution of our microscope objectives and DMD, and stability tests for the objective mounting structure.
