Optimized Algorithm for High-efficiency Atom Transport

Zane Crawford, Michigan State University

Current work at Sandia National Laboratories includes the creation of arrays of neutral atoms for quantum computation, quantum simulation and entanglement-enhanced sensors. An outstanding challenge for this work is creating arrays of atoms in a repeatable way, with no missing atoms. In this work, computer-generated holograms are used to pattern a light field to create the desired pattern of atoms. Furthermore, the holograms are capable of dynamically adjusting to stimuli, such as a desired image of atoms. This is achieved using iterative Fourier transform algorithms, but is computationally intensive. To reduce the time to solution, graphics processing units (GPUs) accelerate the procedure to create the holograms. A study on the performance of this method is presented with respect to quality of the holograms and the time to solution. Experimental results also are presented to show the utility of the method.
