Progress towards reconfigurable atom array assembly with projected optical tweezers

Reconfigurable atom array has been a versatile platform for many applications, including quantum simulation and scalable quantum computation. Here we discuss our innovative approach to creating fully-populated atom arrays with projected optical tweezers, an integral component of the Quantum Matter Synthesizer (QMS) quantum simulation apparatus. In contrast to the conventional method of generating tweezer arrays with multiple RF tones using Acoustic-Optical Deflectors (AODs), our scheme employs dynamical projection of laser light on a digital micromirror device (DMD) through a high-resolution optical microscope. This technique is highly scalable to many optical tweezers and permits merging and splitting of the tweezer potential. Furthermore, it can be integrated into optical lattices with sub-wavelength spacing to perform Hubbard-type quantum simulation. We will detail the current progress on the DMD-based tweezer generation and characterization, atom loading and rearrangment.
