Abstract: Multipartite entanglement is the key resource for quantum computation. Ultracold atoms in optical lattices provide a clean and tunable platform for generating scalable entangled states. We report the experimental progress on the creation and detection of atomic spin entanglement. Our experiment represents a fundamental step towards quantum computation with ultracold atoms in optical lattices.
