Abstract:
“Neutral atoms are a leading platform for quantum science, witnessing numerous breakthrough experiments in quantum simulation and computation in the last years. Dual-species atom arrays are a new frontier, promising new opportunities such as richer interaction regimes, mid-circuit measurements via species-selective readout, and simple paths to Floquet quantum simulation.
In this talk, I will present our recent work on dual-species atom arrays, both theoretical and experimental. After introducing the platform and setting the physical framework, I will first present some theoretical results for globally-driven dual-species arrays, including methods to implement universal quantum computation [1] and to engineer discrete local dynamics [2]. Then, I will give a broad overview on Quantum Cellular Automata, and I will present experimental results on implementing such models in a dual-species array featuring up to 35 atoms of Rb and Cs [5]. Finally, I will conclude with final outlook considerations on future directions.
