    "abstract": "In this paper, we propose a way to achieve protected universal computation in\na neutral atom quantum computer subject to collective dephasing. Our proposal\nrelies on the existence of a Decoherence Free Subspace (DFS), resulting from\nsymmetry properties of the errors. After briefly describing the physical system\nand the error model considered, we show how to encode information into the DFS\nand build a complete set of safe universal gates. Finally, we provide numerical\nsimulations for the fidelity of the different gates in the presence of\ntime-dependent phase errors and discuss their performance and practical\nfeasibility.",
